Of course Chauncey can get it done. As long as he stays free of injury (and he is not an injury prone player).
Mike D'antoni needs to make sure he doesn't burn him out. A 34/35 year old player should not be playing more than 30 maybe 32 minutes per game on a regular basis.
We do need complimentary role players to fit around our 3 guys right now. A couple of veteran players with young legs would be nice. And another SG who can spread the floor and make the extra pass.
I really wish the NBA/players would hurry up and sign a new deal, apart from the draft which is not really very interesting this year the NBA basically died this week.
