People always bring up the fact that Griffin was a former champ at LHW, but they always neglect to mention that Griffin was an extremely easy style match-up for Anderson lol. Having a belt around his waist doesn't change that. Cause, y'know, clearly one of the best counterpunchers in MMA history is in for a stiff test against a soft-hitting dude who just comes forward alternating punches, throwing in the occasional rear leg low kick to the outside thigh, and hoping for the best. His other 2 wins at 205 are Irvin and Bonnar, who aren't the worst LHWs he could have fought, but they're hardly the best, either.
OT, I'd say Rockhold could easily beat LHWs like Shogun, Jimi Manuwa or Feijao. I could see him beating Bader with relative ease if he was able to stop (or otherwise counter, perhaps via guillotine) Bader's takedowns.
