Skipping ahead and will repost/talk more about it for sure, but I have a very strong lean on Diaz/Silva.
I think the over (or fight goes to decison) will end up having terrific value if the books don't give it a crazy expensive price.
On first glance, Nick looks like a tailor made victim for Silva's counterstriking. Nick always moves forward, and Silva has feasted on guys that do that (especially, if like Nick, there's not much threat of a takedown). But the thing that makes Nick different is that he NEVER commits to throwing any of his punches with power. He doesn't sit down on them almost EVER, so his pitter patter jabs don't leave him too open to getting hit with huge counter shots as often as you'd think they would. He's hittable, but generally it's been by guys who are more willing to press the action and come at him. Silva prefers to sit back and counter, which is more difficult than you'd think vs. Diaz.
Throw in that Diaz is CRAZY tough to finish even when he does get tagged, has a terrific guard in case he ends up on his back, and I really see this fight going the distance.
And even though I actually think Diaz is a bit overrated overall, in some cases styles make fights (right Barry the heater?) We don't know for sure what we're getting in Silva with his comeback, so I may make a small play on Diaz su as well.
For those with the option, NOT Silva itd would be the play to make imo.
