Iverson simply gives team's another viable scoring option, and a couple of steals and assists. He's a good enough all-around player to not hurt you on defense, and more than make up for his short-comings on offense.
For a team like the Lakers, that is already complete he just improves their depth at the very least. But because he can be a prolific scorer who can take over a game, he give the Lakers two players who can do that. You can't control Iverson without doubling him, and you can't control Kobe without doubling him. You can attack from both sides of the court and make it impossible for teams to effectively cover both without creating a wide-open shot for the other players.
I think he would make the Lakers offense unstoppable, even more than it already is.
But the Sixers need him a lot more, and if they sign him, I'll be very pleased. He would have been redundant here if Lou Williams could play, but with a broken jaw, it will be a while. He's still a more explosive scorer, however, and should be able to finally complete the Sixers orginal master plan. That plan was to pair Iverson with a reliable inside scorer. I say they now have two of them with Speights and Brand. It's a little late in Allen's career but it could work. Sixers have plenty of scoring options now, so they don't need 30 from him every night.
My point is that a lot of teams would be better of with Iverson, but they have to want to upgrade their play at their guard spot and be committed to it. He is pointless to have if you don't want to play him, and it seemed to me both in Detroit and Memphis the coaches didn't want him. That isn't Iverson's fault. It's stupid to think he can't produce any longer if he isn't given the opportunity. It's insulting to think he should be a back-up guard in the NBA, until his play shows that is all he's capable of. At the price he was forced to sign, any team in the league could pick him up. For what he gives in return, why would any GM not sign him? He doesn't make sense on a young team that isn't ready to contend. He makes sense on a team that is ready now and needs more scoring. He's be great in San Antonio with Popovich, and might even be willing to come off the bench there.
