Isn't Nick being offered $175,000.00 to fight Lacy? Which is about what he makes in his MMA fights. Personally, I think it's kind of a cool idea because I'd like to see how he matches up to a pro boxer, granted Lacey is past his prime, but if it's about the money, 175K isn't worth the risk to Nick's brand.
In my opinion, Nick loses to Lacey and assuming that's the case, I don't see his cash cow fight with GSP coming any sooner if Nick returns to MMA defeated. I don't see that as a fight Dana would be eager to promote. I'm a Diaz fan (both brothers), don't get me wrong, all my past posts would support that, but if it's a solely money issue, getting paid for a risky boxing match for what he's being paid in MMA already isn't worth it. If it's for the challenge because he's bored of MMA, well, that's his prerogative and can't hate on that.
I'd like to see the fight with him and Lacey, but I'd much rather see a fight between him and GSP and the chances of a super fight with GSP goes down in my opinion if he goes through with the Lacey fight.
