It's unfortunate that Rich's injury forces all of these fights to happen.
Were he healthy, the UFC would probably be better served by offering up at least two of these guys for title contention before they have to take a loss. The round 2 loser will either get a title shot coming off a loss (possibly against the guy that just beat them) or have to fight to get legitimate again.
If Rich does lose I suppose Jeremy Horn can enter the mix as well. If he wins his next two defenses, and Chuck does as well (which is not terribly unlikely), I think Rich would be the next logical choice for the LHW title shot, although I doubt he would take it.... definitely a fight I'd like to see though.
