The reality is this, with Daniels out and TA getting healthy, it was an absolute no-brainer that he would get time off the bench.  For those whose hatred borders on irrational, suggesting JR or Lester would get that time shows a complete lack of baskbetball awareness in my opinion.  Has Tony made some boneheaded and headscratching decisions in his day?  He sure has.  But he also brings something that few players on NBA benches can bring.  An instinctive athleticism, both slashing on offense and anticipation on defense.
It is obvious, to me at least, how much talent he has compared to many NBA players, despite his obvious flaws.  Many of the players people wish would play, may not make Tony's mistakes, like Scal, but have absolutely zero possibility to bring something unique to the table like Tony does.  Not making excuses, but since Tony is the type of player whose talent is making things happen, not standing on the weakside and playing off of teammates creating for him, he is bound to make turnovers and mistakes.  Nobody was screaming louder than I was during the Bulls series last year when he was in there, but realistically, it was a situation destined for failure.  He was out the better part of 3 months, then was asked to come back and play spot minutes, sometimes in crucial parts of the game.  Scal was able to do well, precisely because he is a limited player who does not try to do too much.
This is the regular season, not the playoffs, playing many different teams sometimes in a grueling stretch.  Tony adds energy, athleticism and talent off the bench that the C's don't have otherwise.  He has shown better decision making these last few games.  But even if that suffers, it is still a no-brainer for him to get minutes right now, he brings too much not to play him.  He wont be used as the 5th piece late in games, hitting spot up Js, a la Posey.  However, he will spell Ray and Paul during the dog days of the season, and they don't lose much if anything during the 2nd and 3rd quarters when he is in there.  In fact, nobody else on the team could have finished that play from House last night.
