Ok so if the Celtics don't win it all this year would you make this Trade?
Scal, Perk and Tony allen

No.  With KG at PF, the Celtics need a C that is a better man on defender at C, not the great weakside blocker/defender.  
Rather the Celtics go for a cheaper option as a 2nd C to compliment Perkins.  (I would love to find a way to add Diop)
Plus, there is no chance the Celtics will add a fourth near max player.
