I collect jerseys, and love it!
I won't list them all, but here's some highlights (and lowlights) from my collection:
Pat Swilliing, LB, New Orleans Saints  - loved watching him rush the QB back in the day.
Eric Dickerson, RB, SMU - I have both the home and away.  Rockin' it in the picture below with Chris Mortensen.
Barry Foster, RB, Pittsburgh Steelers - I also have a Panthers jersey of Foster.
Walter Payton, RB, Chicago Bears - my favorite player of all time.
Charlie Garner, RB, Philadelphia Eagles - love the old school Eagles jersey!
Errict Rhett, RB, Tampa Bay Buccaneers - old school
Marshall Faulk, RB, Colts/Rams/SDSU - 2nd favorite player of all time.  I still have the sportscenter on video from when he turned pro.  Also have the one from his 386 yard 7TD performance against Pacific.
Garrison Hearst, RB, Arizona Cardinals - I've got a soft spot for Georgia RBs.
Ricky Watters, RB, Seattle Seahawks - old Seahawks logo
here's some jerseys that never leave my closet:
Cecil Collins, RB, Miami Dolphins - the night I got married I watched him run all over Auburn when he was at LSU
Jason Thomas, QB, UNLV - I have both home and away.  He couldn't even make it as a TE with the Ravens!
