Bynum has a degenerative condition that isn't likely ever going to truly be better again. Bynum was only 25 years old last summer, but his knee was 45 years old. Seemed like he might be able to play two dozen games if he rests for a year, but his condition will come back pretty quick once he starts playing an NBA schedule, regardless of how much rest he gets or what skill set he brings. He also seemed to have a number of emotional issues that made him a problem in practice and the locker room. It was bad news & he practically ruined last season by his mere presence. If you didn't like Mike Brown, you should send Bynum a thank you note. While Bynum isn't the only reason that Mike Brown is gone, he was a big contributing factor for sending the season into the gutter, which is why Brown got fired. But if the season hadn't gone sour, the Cavs would not have had a had a chance to win the lottery, which gave the Cavs a chance to get Lebron & Love. Damn, that gets complicated. Maybe we should all send Bynum a thank you note. No idea what to make of last season any more. Maybe it was like keeping a low pair in draw poker and picking up 3 aces. It all seems to have worked out in the end.
Haywood has had locker room issues in his career(ask Etan Thomas) but he seems like he's grown out of that and his foot condition seems like has a pretty decent chance at a full recovery especially if he keeps his weight down. The question with Haywood is whether or not he will have any skills left when his foot heals. Two years ago, Haywood looked like a serviceable decent defensive center for 20 minutes a game, even thought his offense had evaporated, either because of age, or because he was playing on a team that lacked scoring threats. But the difference between 33 and 35 years old can be vast in the NBA, so it's really hard to say if the Cavs will get a reinvigorated Haywood when he returns to the floor, or if they will get a shell of the player formerly known as Brendan Haywood. Cavs will probably know by the end of training camp. They only need him for one quarter and 6 fouls every few games, so it seems there is a pretty good chance that he could fill that job. My problem with Haywood is that I'd be surprised to see him step up and play two quarters of replacement level basketball for 50 straight games. That's what the Cavs will need if Andy has an injury. So my guess is that Haywood should be a decent situational role player when the team wants to play big, but I'd be surprised if he's real strategic depth for the team.
It would be great if the Cavs were able to make a trade to get better front court depth, but as of today, it looks like the Cavs are going to sit tight until the and keep their trading assets in the bank (no Timofey) until they see what they got in training camp.
