I'd have to agree with Snipa for the most part, in football you have to break it down by position:
QB: Montana
RB: Jim Brown / Barry Sanders / Payton / Sayers
WR: Jerry Rice / Lynn Swann
TE: Ozzy Newsome
OL: Jim Parker, Stepnoski, Williams, Art Shell, Bill Fralic
DL: Reggie White / Clyde Simmons / Mean Joe /
LB: Tommy Nobis, LT, Butkus, Nitschki (sp?), Jack Ham
CB: Nightrane Lane / Deion Sanders / Rod Woodson / Herb A
FS: Steve Atwater
SS: Ronnie Lott / Paul Krause
