This fight would be awesome. I would actually be rooting for hendo. I see Fedor winning but if Hendo can connect one of those overhand rights, Fedor might be in for a rude awakening. Same if Fedor connects also. Would make for an interesting matchup for sure.
Uhm did you see how hard Rogers hit Fedor? Arlovski, Rogers, Sylvia, Hunt, Fedor has a massive list of people that hit way harder than Hendo and to be honest I don't think its actually physically possible for Hendo to knock Fedor out.
