This weekend we have a major matchup featuring a fighter who many consider the second best welterweight in the MMA and the return of a former champion to the division after failing to regain his lightweight dominance.
At UFC 127, Jon Fitch vs. BJ Penn presents a very interesting fight. In Fitch, you have a man who is literally the poor man's version of Georges St.-Pierre. He likes to grind his opponents out which might be severely boring to many MMA fans but has been effective none the less.
On the other hand, BJ Penn is at a bit of a crossroads on his career. Dropping two decision losses to Frankie Edgar, both of which were for the 155 title, Penn is now 32 years old and looks to be making one final run in the sport before possibly contemplating retirement.
The problem with these two is that in either case, the winner has already been beaten by GSP and a rematch in either instance would yield a similar result.
