These games are the reason I believe giving the max to IT is a tough question (as it is in other forums outside this, where we are biased Celtics fans).
When he scores 53 and his pair scores 40, well...he is a God and he is beating franchise records and making history and those great stuff. Don't remember he's been scored 40. However, in games he is dark in offense, and there are a good number, he keeps being abused in defense and this breaks the team balance.
And this is not overreacting after a game, it's what I've been keeping since I write here (and many has confronted me just for this opinion, which you may or may not share, but it has its point).
