Jardine's longevity in the UFC IMHO, is due to his not being able to say no to a fight. Most others pick and choose who they want to fight, The Dean is one of those throwbacks that REALLY will fight anyone they put in front of him. Dana's got to have some appreciation for that right?!?! I mean on paper, Keith shouldn't have had to fight Houston Alexander, and could have said no, but about half way thru the first round, we see why we don't rely solely on paper (that monkey stance was kinda weird though).
I really like Keith, but I think he's unintentionally typecast himself as journeyman light heavyweight. Anyone who fights Jardine will be measured as to whether he's gotten an impressive win or respectable loss against The Dean.
I agree with morninglightmt, take a few months off, recoup, recover, and re-invent The Dean of Mean.
