GSP is just so good on the ground...I don't see Fitch posing any danger off his back and I think that's where he'll be within a minute of the fight...from there he will probably be GnP'd and eventually submitted...
however, if Fitch can show us some awesome TD defense and use his size to sprawl effectively....we could very well have an extremely competitive fight
I completely agree with the first part of this statement. I don't think Fitch can hang with GSP on the ground. However, I think it may take more than a minute to get it to the ground. I'd imagine Fitch will be expecting it, and try to stay on his feet a bit. But I think GSP has the edge there as well. GSP has very technical striking.
Should be good fight.
Oh, and props to the OP. Great post.
