However, unless you're like Fedor, ( someone, bright, and technically advanced) there are limits to what your skills can overcome against being over sized and over powered. Fedor has a limit too.
It's really hard to say if Brock's skills combined with his huge size advantage are enough to defeat Fedor. To be honest I hope they never fight. I'd rather see Brock fight someone like Bobby Lashley and pit fedor's skills against opponents closer to his size. He's fricken awesome.
