A member of the 2008 NBA Championship Team, Kendrick Perkins arrived in Boston as part of a draft-day trade.  Kendrick, who was drafted late in the 1^st Round, would provide an above-average defense to the Celtics and he would have two straight top five Defensive Rating finishes (2007-08 & 2008-09).  Perkins would act as the team's enforcer if need be and that toughness is hard to quantify, but we hope we did so appropriately on this list.
