I believe PK was just part of the changes that went on when Coach Perkins left at end of 86 season- Steve Sloan came on board as AD and hired Eli that season. IF my memory serves correctly.
For all his shortcomings as a HC Mike Shula will hold a special place in my heart for that 85 season- 9-2-1 is not the greatest season ever, but that team was awesome and so close to undefeated.
