Archie Manning.
I honestly don't know if that is true, but lots of older folks in my family swear he would have been one of the greats had he not played on terrible teams in New Orleans. And that's coming from an LSU family that hated to give any credit to an Ole Miss player. I'm just old enough to remember him playing in 1980 and when he went to Houston, but I can't say I knew enough at that age to know if he was good or not.
