Jay Glazer did an interview before the SB about his MMA training programs where he pointed out that the conditioning is the real benefit, and most players don't cope well with the fighting side of the sport. They are damn near naked compared to all the NFL protective gear they wear in their combat.
However, there were a couple of NFL players that he pointed out as being MMA studs, and one was DeShawn Goldson, then of the Niners. In the beatdown on Harbaugh's birthday, Goldson had two plays that reminded me of his MMA skills. One, he got crunched by Lynch after a nice gain, but used Marshawn's momentum and tackled Lynch by his HEAD. THe other was the body slam and takedown of Baldwin. Culliver got the personal for drilling Baldwin in support, but the truth is there was nothing illegal I could see.
There are three clear benenfits and one drawback to this training.
Browner's already bad man reputation will be further enhanced, and scared receivers seem to have short arms. Really, if you are not a tough guy yourself, watching film of Browner the week before facing him will make the yellow stripe pretty obvious to all by about the mid first quarter of gameday.
Browner is in a contract year of sorts, he could be tagged or designated RFA, and being in peak physical condition can only make him more money. Browner wants to get paid badly. It comes through in the interviews of him I have seen.
Browner might actually have the chops for the Martial side of the sport, and there are places on the field for using an opponents momentum against him.
The drawback? Browner is already a must watch for officials who are flaghappy for hits that look mean. Browner has had a problem already with being grabby with his hands. MMA is not going to teach him not to grab some jersey now and then, far from it, MMA features those tactics.
If I my druthers, all players would crosstrain some. I think all Oline and Dline players should have some wrestling training.
