212 lbs? Way too skinny for a guy 6'6" fighting at heavy weight. The only way I see Wilder winning this is if he stick and move all nightand somehow tires out Fury.
Could seriously improve himself if he gained some girth on his legs. Always had the feeling his team were not the best, but coming in so light suggests to me a real lack of pragmatism. Clearly diet him out a textbook, eating what is thought to be all the right things but his body, it would seem to me, needs something different.
He definitely could. Dropping ~12lbs of water weight isn't a great deal for a professional boxer. Despite the supposed illness, I didn't think he looked particularly dry against Ortiz (@214lbs IIRC), he's just a very wiry, lanky athlete.
With all that nervous energy wilder has been burning off the calories, he will be a welterweight by fight night.
Fury 258 Wilder a surprise Baby Miller-esque 320... ... then he remembers to take his gold off and hits 220
