Overall I'd say Herschel Walker. We thought 'wait til this freshmen gets hit and finds out he's in the SEC'. We thought wrong.
The best Vol may well have been Condredge Holloway, or maybe Heath Shuler or Jackie Walker or Chuck Webb or Stanley Morgan. Bobby Majors, Dale Carter, Larry Seivers, Reggie Cobb and Chris Mims aren't far behind. We've been lucky to have had a lot of great players wear the orange.
Other opponents of note were Marcus Allen, Hugh Green, Ronnie Lott and surely one or more which don't come to mind right now.
