It would work, because it would give the team depth at the guard spot, a major sore spot last year.
Plus, you have an aging point guard in Kidd who will be effectively only in limited minutes, and you can't expect Shumpert to start playing 35 minutes right off the bat.
Last year, we had three guards go down with major injuries - Shump, Davis, Lin. This year, with Lin, we'll have two guards coming off of injury, an old point guard, and a fat out of shape point guard.
This team is old, and so depth is essential, with injuries inevitable to some of the old timers (Thomas, Camby, Kidd).
