Hey everyone, it's A.C. here! What's happening?

Sorry I haven't written this summer, but I've been on the IR while I recovered from a knee replacement.

It was something I've had to do because it's been hurting me for almost 30 years now. When I first hurt it, people don't realize that I played the next five years with no ACL, no MCL and no cartilage in my knee.

I remember when it happened: I was trying to change direction, and for some reason my foot didn't go with my body. And it just snapped right there. We were playing Kansas City. I didn't really feel that bad with it that night. But I had to have another corrective surgery and I was only able to really strengthen the muscles around the knee. I limped for the next five seasons.

Then one night, I remember I was playing against Otis Birdsong, and he went by me so fast that I said, ‘It's time for me to leave the game now.' I couldn't react fast enough. It was my tenth year in the league and it was just too much pain.

I used to carry 30 pounds of dead weight on the road with me and as soon as I got to the hotel room, I'd lift, lift, lift. At home, I'd have 30 pounds in front of the TV and just continue to lift. I had to do that for five years just to play. And it just got to the point where I got tired of rehabbing.

After I retired - playing golf on it as much as I was - after a while the doctor said the knee was just going to collapse. So I finally had to have this done, just to get rid of the pain.

The way I see it - and I'm not one to complain about what happened because I'm more of a person that, whatever cards I'm dealt, I'm going to find the best way to make them play right - but the injuries cost me a lot of production, and a whollllle lot of money. And possibly a position in the League's Top 50, had I been healthy.

But I don't cry over spilled milk. And it turned out for the better. Cleveland's my home, and I love it here.

Enough about me, let's talk a little about the Cavaliers and LeBron's great run in the Olympics ...

Obviously, I'm very excited about the addition of Mo Williams. He's something this team has really needed. 

First of all, if you've noticed over the past couple seasons, the Cavaliers have been looking to push the ball up the floor. Now, we have more than one person to push the ball. And we have two guys now who can beat you off the dribble.

Now, what that does: you can't double-team both of these guys - Mo and LeBron. So you're going to have to guard them with "half" a guy - hedging and cheating. That's going to give other guys the opportunity to get open. It'll give a guy who's a jump shooter an extra foot to get a shot off. These are little increments that we're talking about, but they're big in the scope of how things work on the floor.

I've heard the argument that Mo Williams isn't a good defender, but I'm not sure I buy it. And he's heard it and is aware of that.

He played on a team that was known for not playing defense. That doesn't mean he can't play defense. Everyone that plays with Phoenix - they said none of those players could play defense - but you saw that Shawn Marion did pretty well when he went to Miami. He was pretty defensive-minded there.

To me, if you're an athlete, you can play both ends of the floor. You see what LeBron has done with his defense since he's been focused on it. I just think Mo will focus on it more because Coach Brown is going to make him focus on it.

As far as what this means with the Delonte West situation, this will probably give the Cavaliers more leverage with Delonte. But really, I don't see anything wrong with Delonte, Boobie and Mo in your backcourt and coming off the bench. That's a nice set of guards.

And I think Mo's presence is going to help Boobie a lot. Because even though the coaches are teaching Boobie to use his dribble to get guys open, watching Mo and guarding him in practice will help Boobie understand how to use his dribble to get things done. And I think he's the one who'll benefit most from playing with Mo - because he's going to see firsthand how to use his dribble to get himself and other teammates open.

While he's away in Beijing, LeBron said he was happy about the trade. He hasn't had too much to be unhappy about during the Olympics. You watch him and you can tell: He's a man among boys. He's the leader because his play has made him the leader. He's leading by example.

He's doing some things that I haven't seen done in a while, like that play against China where he just caught that shot in the air. You can see his dominance is not just in the physical part of the game, it's the basketball IQ.

You can see guys out there are "system guys" and they don't always do well in the Olympics. Some guys are system guys, like (Carlos) Boozer. He's a "system guy." He's not going to play well in this surrounding. You have to be able to "see" things and he doesn't see them now that he's outside his system. Dwight Howard is like that. He has to see it. LeBron doesn't have to see it to understand it. He's a special human being.

Again, aside from the physical aspect of the game, LeBron has been gifted with two things: basketball IQ and common sense. He has the ability to listen well enough to understand things right away and make the right decisions. Guys that age who are suddenly making that kind of money get foolish and arrogant.

He's a very mature individual for his age. And he never forgets where he came from. But, unlike a lot of athletes, he doesn't let where he comes from control where he is. A lot of guys get caught up in helping out everyone they grew up with and they don't realize that these people are not their responsibility. They had a different mother and father.

A lot of these young guys bring these people with them because they don't know how to be social human beings outside of their small group. But LeBron's not like that. He remembers his background and his past, but he never lets it control his present.

When LeBron gets to Camp, the team is going to be a little different than the one he left last spring. I still think there is going to be another move to balance the frontcourt in what we lost in the deal for Mo. Right now, we're not balanced in the frontcourt.

Sooner or later, you're going to have to find someone to back up Z. That's something we've been missing. I'd like to see us get a legitimate backup at center, so whoever is the backup power forward can concentrate solely on being a backup power forward. But we usually have a dual-purpose guy at that spot.  That shows you how hard it is to find a good center who can play with his back to the basket. It's a dying breed, a lost art. There's Z, Shaq and Yao. And everyone else is a hybrid. LeBron's a hybrid.

When I played, if you were 6-8, you played under the basket. You were not going to handle the ball. The coach would put you on the bench if you were 6-8 and tried handling the basketball. It's a different world now.

I'm thinking J.J. Hickson could get some quality time this season. He had a real nice Summer League and I understand he did very well in Pete Newell's Camp, as well.

What I like about him J.J. is that everything is around the basket. He loves to mix it up around the basket, and I like that. That's what we need - someone who likes to get down and dirty around the basket. That's the game when you get down to it! LeBron and Mo want to make that pass to a guy who plays that way.

Either way, the Cavaliers will be a different team this season, and I think a much better one.

I think you'll see the difference in two ways - although it's hard to figure these things during the off-season.

One is, with Mo and LeBron, there will be more pushing the ball up the floor, and more fluidity off that push. I'd like to see them just go right into their offense. That's why you have to have everybody aware of every position. Because if you have Mo pushing the ball up the floor and LeBron ends up in Z's position and Z ends up in LeBron's position, they have to be able to still flow into the offense and run it. Because that keeps the defense off-guard.

And defensively - I feel that we're a good defensive team because we help well. But one thing we're going to have to develop this year is to focus on individually stopping your man. The help is there. But they have to focus on stopping their man - especially in terms of dribble-penetration.

Those are seemingly small things, but they will help us become a much more solid basketball team. And those small things can sometimes be the difference between going home and winning it all.
