I thought about Rogers and Edwards, but seemed like Tim Raines to Fitzgerald and Carter's Rickey Henderson.
Rogers and Fitz played 2 years, with Fitz having 25 more catches and 7 more TD.  So while Rogers was great, I don't want to put people on the list just to put them on.  If only 2 years of volume doesn't bother you, I assume you're voting for Fitzgerald.
Same with Edwards and Carter as UM players.  If you see a few guys as mostly equal and are going to go with a Michigan man, won't most go with Carter?  
I could post 20 guys for each jersey number for people to reminisce about, but we don't need a bunch of 2nd-best types on here, do we?
