6 pts and 8 rebounds in almost 30 minutes. That does not look like the HOF #s he was putting up here in Boston. He must still be hurt. 
I am still waiting for someone to show me the examples of the posts where people called Perk a hall of fame player, compared him to Bil Russell, etc. However, since none of those exist, I won't have to hold my breath waiting.
14-6 versus 11-9 since the trade. I would take that. Celts would be tied with the Bulls for the 1 seed if they had been 14-6 over those 20 games.
If the Celts hadn't made the trade they might be fighting off the Magic. Look at the Nuggets game after the trade, we'd have trotted out similar lineups to a lot of games.
We may have lost more games while Perk was mending, and would have won more games when he came back. Also, I doubt the team would have been experiencing the same chemistry issues or softness issues that Doc and the players have talked about.
Look, the thing is, Perk wasn't playing when this team was winning and had "chemistry" and "toughness" on the court this year. If we work a little Aristotelian logic, losing a player that was a complete non-factor this season (due to injury) simply cannot be the reason for the issues that are being claimed here.
If anything, we should be blaming our alleged softness on the loss of Semih Erden, which would really make no basketball sense, either.
The softness is from lack of consistent intensity, plain and simple. "Resting on the court" is total BS, but it's what our veterans do
and get away with!
