I'd say Lloyd was an exception that proves the rule, but that particular rule is a couple of decades out of date. LLoyd retired over 20 years ago. Relative to the other players in the league, 228 pounds ain't what it used to be. Lloyd was considered relatively undersized at the time, but he was a fantastic athlete with a wonderful nasty streak. Edmunds is even smaller and there is no reason to believe he could take on linemen the way he would have to.
