good tony is a good sg with some impressive abilities to finish around the basket and play defense.
good tony is a passable pg, based upon his play in the last game, when he has other players to help him out (ray, house, et al) good tony can probably play pg fairly well for 15 minutes a game.
however...
while i do not have deep and abiding reservations about good tony playing back up pg for 15 a game, i do worry a LOT that in about 1/2 of tony's games, the bad tony shows up instead of the good tony.
when bad tony shows up you can expect turnovers, poor decisions, and ball hogging as opposed to ball distribution.
when bad tony is a sg, you can bench his butt. but if bad tony is your back up pg it is more of a problem. pg's need to handle to ball alot, which means bad tony has more chances to make mistakes.
pg is more central to the celtics ball movement game. bad tony would hurt the team there more than as a sg.
so, tony as emergency pg is fine with me. and if doc could implant little nano-critters in tony's brain to ensure only good tony appears, i am all for tony being a back up pg.
but until doc figures out nanotechnology, i hope tony is the emergency pg only.
