I would say it had to be John Cappelletti. Cappy shared his Italian heritage with Joe, was a Heisman Trophy winner, had a family that adored Joe, and vis-a-versa, and Joe was extremely caring to the Cappy family over his brother Joey's situation. My guess is that Cappy was the kind of kid that Joe could relate to most as his own son who made him proud, and it showed! BTW, I believe that Jay made Joe extremely proud too, despite the awful way he was treated by some fans, especially on this board!
