This is a pretty solid starting 5. I'd keep these the way they are. Ray Allen might be your first guy off the bench because of his FT and 3PTs, and I'd mix in Z on the days Shaq gets hurt (he's bound to miss 10 games a yr). Rasheed Wallace is great because of his block shots. You have balance overall.
One guy I wouldn't start too often is Allen Iverson. Talk about a 1-dimensional player for Fantasy Sports! PTs, PTs, and more PTs. That's nice, but historically his FG is in the upper 30% to lower 40% range, he doesn't rebound, and doesn't get a lot of assists. An occasional steal from time to time (too old now to get them consistently these days). I'd package him and maybe Magette for someone who might get you a ton of assists, like Jose Calderon or someone like that. A.I.'s playing on a terrible Grizzlies team that already has OJ Mayo and Rudy Gay taking shots away from him, which actually means he's probably gonnag get only 15 pts/game and that won't make him worth a roster spot if there's plenty of other free agents who do a lot more than 1 thing.
Anyways that's my beef on A.I. I'm harsh, but I have to be when I pick my guys too! Other than that, I LOVE your lineup. How can you lose with Kobe? Good luck!
Oh yes, 8 out of 10. Nice!
