Personally, the Lakers need to stick with George & Fisher. I think they need to let George start as long as he makes a comitment to working on his game, especially his ball handling and shot selection. He also needs to not make silly fouls if the Lakers let him start. If he will comit to that, I think he deserves a chance at starting, because he needs a chance to develop. If he successfully developes, him and Kobe will be running mates. Also, George fits in better in a run & gun offense. So if he can learn now how to play 1/2 court, which he does well now, then when Shaq is gone, he will will be able to play both styles.
As far as Fisher, his record speaks for itself. However, the time has come that we need a better pg, but we need Fisher's intensity and defense, so we need to keep him, to develope our bench.
We also have a couple of other good players that we need to keep, Pargo & Medvedenko. I'd much rather send Rush away, before any of those players.
