Interesting. I didn't watch all of TUF1 and I know it wasn't a true tournament format then so I don't know if Swick even won a fight. I've just seen his fight with Stephan Bonnar and Swick more than held his own with the much larger man.
I also think they cut Manny way too quick. He got caught by a good striker because of his poor striking defense. That was a good lesson. Then he lost a tough fight to a very good, very well rounded fighter who is much better than his record in the UFC.
While both Gray and Lauzon have better records, especially when you compare who they've beat and lost to, both have also been finished. Granted one was by himself and one was to the #1 contender but Nate's only loss was a decision loss due to inadequate rules and a conservative opponent.
Talk is cheap...because supply exceeds demand.
