To be honest I'm not that bothered about GSP being out of competition for a while, the guy only fights like twice a year anyway and is hardly going to step up his fighting schedule anytime soon.
I would be interested in seeing him coach, he just seems like a very interesting personality and this is one way of showcasing this. Although I would (personally) only be interested if Koscheck was the other coach. He has a better team than Daley (and is therefore able to call on better assistant coaches/guest coaches). Plus the USA/UK "rivalry" has just been done in TUF.
Granted neither would really have a chance against GSP in the eventual fight but that hasn't stopped the UFC before in the case of BJ Penn vs Jens Pulver, Serra vs Hughes, Tito vs Shamrock and Bisping vs Henderson.
A Diego/Kenny TUF would also be interesting (as someone mentioned before). Especially as one of the reasons for a WW coach was the fact that it hasn't been done in a couple of seasons. A lightweight coach hasn't been done since a season before the last WW coaches, so are therefore even more overdue. Plus them both being TUF finalists would add a nice little touch to the program.
Well, that's it rant/first post over. Looking forward to new TUF season (as one of the few I think). The embarrassing thing is that T'm quite new to MMA and TUF10 was my first taste of it and I'm still in the process of catching up.
