Payton's good and all, but he's not getting any younger, and his defense is killing us. In the Knicks game, when any of the Knicks' PG's did any kind of drive to the hoop, another player had to help Payton keep track of him, which left a guy (Crawford) always open.
Banks stays with his man, he pressures them, and steals balls like candy from a baby. He's not even a bad shooter and a GREAT distributer, if not our best right now. He can take apart the whole defense.
West on the other hand, I don't know what he is. Recently he didn't look like a Point Guard, nor a Shooting Guard. Right now, I think he's best suited for Bench Guard, as with him on the floor is like playing with 4 men. The offense doesn't go through him (because he can only make simple passes) and being a spot up shooter isn't going well now either. If Doc benches him, lets Banks get the backup minutes, maybe it will light a fire under Wests' ***, but as of right now, he hasn't shown anything.
