Not surprising. He is really big for LW. Actually isn't he big enough to where he won't even say how much he cuts? Think I remember him kind of avoiding the question when Joe Rogan asked him after a title fight (Edgar 2 maybe).
I don't know if he is the biggest LW though. Gleison Tibau is freaking huge. Think I remember him saying that he cuts from ~185lbs.
