And if in correct TJ wasn't even supposed to be fighting Renan. Didn't TJ step in for an injured Assuncao?
Assuncao got the first offer, yes, but he wasn't fully healthy, so he never signed on the fight.
TJ Dillashaw got the title shot because Barao recently beat Wineland and Faber, Cruz and Assuncao were too hurt to be ready to fight by UFC 173, and McDonald was coming off a recent loss where he got dominated to Faber (whom Barao had beaten just over a year ago).
That essentially means that 5 guys were higher priorities than TJ in terms of getting a title shot. 3 of those men lost to Barao with much better odds, bigger wins, and more prestige.
And yet TJ Dillashaw is the one to beat Barao in a fight that was seen as a "stay busy", "stat padding", or even a "tune up" fight for Barao.
It just goes to show you how crazy this sport is, and how crazy underestimated TJ Dillashaw was.
Nobody saw one of the best MMA strikers of all-time being dominated for essentially 20 minutes in striking losing via TKO the way he did. Nobody.
Normally saying "nobody" is hyperbole, but that's pretty much true here, and i's insane.
It just goes to show you how unpredictable MMA can be sometimes.
