I think that Brown needs to develop a better ground game.He kept trying the same Guillotine and Faber kept getting out of it.He needs a Kimora or something else.Faber couldn't prevent Brown from taking him down pretty much at will,but his ground defense was good enough to not tap out.If Brown's ground game wasn't so one dimensional,Faber would've tapped no later than the 3rd.
Also,was it me or did Brown look slower than he did in the first fight?I know he's not the fastest guy,but his punches looked so slow.
