Apologies if this topic has come up recently; if so, I missed it.
It occurred to me today that NOT ONE of the UFC's current belt holders has defended their title yet, at least not in their current run as champ:
155 - Sherk. 1st defense will be Franca.
170 - Serra. 1st defense will be Hughes.
185 - Silva. 1st defense will be Marquardt. It was supposed to be against Lutter, but Lutter couldn't make weight, so that was a non-title fight.
205 - Jackson. 1st defense will be Henderson.
265 - Couture. 1st defense will be Gonzaga. Couture was previously UFC heavyweight champion, but he hasn't defended his current belt yet.
So here's the question: who will hold their title the longest?
