Not a monstrous size discrepancy, but still an appreciable one. Wiuff cut insane amounts of weight to make LHW, and doing it 3 times in about a month (for the old school Bellator Björn-a-tourney) caught up with him in the final versus a relatively skinny Attila Vegh:
P.S. Looked both dudes' records up to see if they are still active, Attila hasn't fought since 2019 but one of his last fights was Travis Fulton - there's a name I haven't heard in a while, not since he lost to Arlovski in EliteXC 2.0, I thought he would still be adding names to his 300+ fight record. Looked him (Fulton) up and wish I hadn't.
