I feel we have a lot of UFC fanboys trying to hold onto Mir's career.
Mir's reverse Kimura win over Nog has really clouded people's judement. Yes he is dangerous with subs. But before that...look at his sub wins over the last few years. He rocked Kongo then choked him out...easy sub. He kneebar'd the Greenest fighter in UFC history in Lesnar. Who gave him a leg. He sub'd Hardonk....a kickboxer.
If Nog just keep GnPing to victory, no one is this crazy about Mir's subs over kickboxers and a WWE star. And Mir's striking is terrible. He got straight LIT UP by Nog last time they fought with ZERO head movement.
Barnett can out last Mir, he could take him down and do work, he could beat him on the feet. Hell he can easily hold Mir against the cage, as Mir sucks in that position. Barnett has a much better chin as well.
Cardio/Chin means a ton in a HW fight. And people are underestimating catch wrestling in favor of the flashier BJJ of Mir. People seem to forget Sakaraba using catch sub'd Gracie's. Catch wrestling is more useful in MMA than BJJ is. Not sure why people under-estimate Josh's skills on the ground. They see some amazing bone snapping subs from Mir and they get all giddy like a 12 year old.
Mir will not sub Josh. Take it to the bank. And being on bottom doesn't win fights.
