machida is one of my all tme favorote fighters, and I think he won that fight, BUT, I can easilly see how davis could have eaked out the win.
the problem with machida is he seems to have lost that fire somewhat. whereas he was elusive before, he would follow it up with fury and onslaught (kinda like that one time against davis) and do damage. now it seems hes playing it TOO safe, staying back too much. he isnt engaging when the opening happens, its like hes waiting, but guys know now you cant get frustrated and dart in, you'll get switched off. Im not sure why hes changed, his takedown D is so good, he shouldnt be too worried about it. stay back, then explode on guys. do what got you to the dance.
I also think a move down to MW would do him well.
oh and speaking of size, davis is HUGE. damned that guy is huge. everytime he fights I think he looks bigger.
