I swear some of you guys never played organized sports.
Team chemistry matters, if you don't think so, then you probably never played a game past Rec ball.
Perk was a member of the team, a family member and his loss hurt the Celts and was the driving force in the team not getting to the finals. His defensive presence and rebounding alone would of made a difference, but that's not flashy or sexy. Jeff Green, his potential is sexy, but he does almost nothing on the boards and nobody fears him on D. Perk did the grunt work and let the Big 4 do their thing. Doc knows how important that was as does Rondo, PP, Ray Ray and KG. IF Doc says it had an effect on the Celts and he is a NBA vet, a Championship coach and generally known for his BBall knowledge perhaps your sofa-ESPN pundit plagiarism analysis does not hold water?
