Wow, those are all VERY good fights.
But I'm going to vote for Riley Cote
vs. Shawn Thornton
. Wow, that was one heck of a fight! Toe-to-toe all the way. They didn't stop throwing punches. Just unbelievable. And as Smerri mentioned, it happened EARLY in the season, so it really got everyone pumped up about fighting for the whole year, and nobody could stop talking about it. It was that good. Don't forget that round 2 between them was pretty good also. They've had a great "feud" this season, and hopefully it carries into the next.
The rest of those fights were very good too. Barch and May had an amazing fighter feud - probably the best in the league, along with Cote/Thornton.
Here's how I would rank those 6 fights:
1.) Cote vs. Thornton
2.) Barch vs. May III
3.) Tucker vs. Ruutu
4.) Godard vs. King
5.) McGrattan vs. Orr
6.) Laraque vs. Brashear
