Do people actually think Diaz is going to win or is it the odds that are attracting them?
I know Diaz submitted Maynard during TUF but since then Maynard has really tightened up his game. Dude was able to avoid being in danger of both Clementi and Miller who are both crafty grapplers that have better wrestling and striking than Diaz (IMO).
Coupled with the fact that we saw how suspectible Nate is to strong wrestler who don't compromise themselves (e.g., Stevenson, Guida), you would think Maynard should get an easy win. Unless he actually tries to finish Diaz like Kurt had tried and gets sloppy, which I doubt since Maynard has been decisioning all his opponents as of late, then I really don't see Diaz standing a chance.
