Well US team have guys like Jason Dent (went the distance with 2 of the top UFC 155ers in Huerta and Gleison Tibau!). Also they have Mark Miller who beat legit UFC prospects Josh Neer and Brad Blackburn back in IFL!
To be honest, compare the US team to season 6 of TUF! Mac Danzig tore through that season as a LW fighting at 170! and Danzig was completely outclassed by Josh Neer ! (and would be outclassed by guys like Tibau, Huerta and Brad Blackburn too)
Mark Miller and Jason Dent dont even seem to be the best on US team anyway! So I think you guys are really underestimating the fighters this season!
Sure they might not be the best, but neither were the fighters on any other recent season of tuf (6-8) !
