I think that Rashad's and Lil Nog's striking is honestly quite even. Rashad has way better wrestling, while Lil Nog is a little better at BJJ. However, that BJJ advantage ain't gonna net him the submission win over Rashad. If Brilz ( who should have won ) can do what he did against Lil Nog, you better bet Rashad can. Granted, Lil Nog did show slightly improved TDD against Bader and Davis. However, that isn't gonna be enough to stuff Rashad's takedowns.
Overeem is gonna destroy Big Foot. Not much discussion here.
Aldo vs Edgar...ah. Despite how confident I seem to be about Aldo winning this bout, I honestly am not sure who is gonna triumph come UFC 156. Aldo has decimated less than stellar competition, yet has also looked mediocre in the last round against Hominick and the fight against Florian. I think the weight cut is draining his cardio too much, and that won't work out well fighting Edgar. Aldo has superior stand-up, that is for sure. Edgar's boxing is good, but he gets hit way too frequently, and Aldo hits HARD. Thing I'm unsure about is Aldo's TDD vs Edgar's TD. If Edgar is able to take down much larger wrestlers like Maynard and Henderson, chances that Aldo manages to stuff all of Edgar's takedowns are slim. Also, hopefully Aldo's cardio doesn't cost him the fight.
