Lesnar replaces Arlovski. Shields has eleven straight wins including W's over Yushin Okami, Paul Daley, Nick Thompson, and Carlos Condit. Not top flight competition for the weight class but the best that is available. I think he needs to be on the list.
like the AP bball listings you should note anyone dropped off and anyone premiering on the list. also add a collum for previous rank would be kool too. I'm looking and trying to figure out who's changed, but some of the changes have been 1 spot so it's hard to remember (yeah I'm getting old)
