Wow dude maybe I could go to this. I moved last week to outside of Detroit. I was actually thinking of going to the last Fedor fight in NJ since I lived in upstate NY. Not only do I really want to see the fight, but if this was Fedor's last fight, to have my first MMA event be Fedor's last fight (hopefully a win) would be awesome!
As for the fight, it could definitely go either way. I think if Dan uses his wrestling well but is able to stay away from submissions, he could get the decision. It's tough to call on the striking cause both have one punch KO power and either could land it. I think Fedor has a slight edge in the striking, Dan with the edge in wrestling, and Fedor with grappling to work submissions from top and bottom.
Pretty decently matched though. Dan, while 40 years old, is still a top fighter and I think a great match for Fedor who no doubt is not as good as he was but still a top fighter too.
I think they're still relevant enough that a win by Dan over Fedor is a great win for his career, and likewise for Fedor over Dan.
