Browne has been submited 9 times...However he has evolved the most among all veterans...He was absolutely manhandling Silva on the ground and Silva is a black belt...Made it look like Silva was a blue belt.
I doubt Maia can just sub him like others did in the past.
One interesting insight about that fight which seems to be all about wether or not Brown can keep this standing : Maia's takedowns come almost exclusively from the clinch. The only times Brown is taken down is against powerful wrestlers like Hendricks, with a double leg shoot. Brown is extremely strong in the clinch due to his muay thai style, so its going to be interesting to see how Maia can deal with Brown's clinch while trying to take him down and if he can avoid eating knees and elbows in the process.
I can see Maia winning a UD by controling Brown on the ground, but I also see a UD for Brown over a bloodied Maia, possibly a TKO late in the 3rd.
Oh one last important thing : this card is happening in Brazil with all brazilian stars fighting home...expect most of them to be loaded with banned substances thus performing much better than usual.
