You think wade is a better wrestler than charles. You think islam will dominate the grappling, and you think having charles on top of him is no big deal. You're also hyper focused on the felder fight for some reason.
I haven't seen anything to suggest that wade is a better mma wrestler than Charles -- they average about the same amount of takedowns per 15 minutes (wade is very, very slightly higher), but charles did it while facing far better competition, and charles has better takedown defense, and charles is bigger. I also haven't seen any reason to completely brush off the possibility of charles getting on top. Is it unlkely? yeah, but it's a possibility, and a dangerous one.
Are you just supremely confident in Islam's bottom game, or are you just supremely confident that Charles can't sweep him to end up on top and taken him down and end up on top?
