He's not an impact player, he's a complementary player.
Good news: He knows that.
He can score on a bad team (Indy) that needs someone to score, but he's not really a go-to scorer. He won't be the guy to get the big bucket, make the big shot, etc.
He's a good defender, but isn't the Artest/Posey/BigBen-type defender because he tends to use quickness and positioning rather than strength.
He also doesn't run his mouth non-stop.
That makes him a PERFECT fit for this team, which already has alpha-scorers on offense and plays smart team defense. When the rotation shortens, he'll be on the court with either Ray or Paul and KG or Sheed, and probably Nate, so that would be at least 2 or 3 primary scorers on the court with him, rather than the mess of a rotation that Doc uses now. (BTW, I'm hopeful that the playoff rotation will be a bit smarter than the current rotation).
