Its a very interesting fight. Based on what he saw with Rogerio vs Bader and Davis, it makes sense to think that Rashad is the fav. Rashad is the better mma wrestler and striker then both.
Rogerio does have some great hands and solid power and that is something that is a big threat to Rashad who was downed by Silva and Rampage from strikes that didnt really seem that strong, so he is vulnerable.
I know for a fact that Rogerio is training hard and taking this fight very seriously. Aside from his usual training with his team and coaches in boxing and BJJ he is bringing in 2 Russian wrestlers, not sure who to work on that aspect of his game.
Both guys have great hands, Rashad has the wrestling, Rogerio the BJJ.
Gonna be a good one.
