Agreed on th whole, though I think it worth considering the following.
The trouble is that last time they fought, Koscheck got completely owned on the ground, outwrestled by a, on paper, inferior wrestler. He had nowhere to go other than striking, and he got spanked at that too.
As for it being JK's last title shot, I dont think it will be.
GSP is now in the position of having nobody to fight. He has beaten all legitemate contenders in the division, and the matchmakers are going to have trouble making fights that sell tickets involving GSP.
I think what will happen is that GSP will now go dormant for 18 months, maybe even relinquish his belt, while he bulks up gently to 185lbs, to take a run at Anderson Silva in a fight of the generation.
This will leave the 175 division open for some great fights among some evenly matched and exciting fighters. I predict that we will see Koscheck and Dan Hardy trash it up for a fight for the vacant title in 2011.
