Out of 4 key fights at 160lb limit (where weight is known) he lost three and won only one fight (over welterweight Walker). And I heard stories that making middleweight limit for Walker fight hurt him somewhat. I'm certain that had he attempted to fight the above key fights while weighing below 160lb, it'd hurt him also, he needed energy for his style, and it would probably add up several more losses to his record.
How about fights with Al McCoy, Mike McTigue and Eddie McGoorty where he was a middleweight? And how about certain bouts with Jack Blackburn, George Chip, Battling Levinsky, Jack Dillon, Billy Miske, Mike Gibbons and Tommy Gibbons? Was he above the middleweight limit for ALL of those fights?
Sure, Greb had most of his important fights weighing more than 160, but saying all he pretty much did that was significant at 160 was to lose a bunch of times to Flowers and beat a welterweight I think sells him short.
