You've also got the aging legends like Fedor and Machida. That brings it to about 30 fighters who could potentially be elite UFC fighters if you wanna take 1 or 2 off. There was a time when this number would be like 2 or 3. Their roster doesn't "fucking suck".
At HW, LHW and WW their depth is competitive with the UFC. At WW UFC is only clearly better because that's the UFC's best division. If it wasn't Bellator's WW would be better cause it's loaded. MW is weak for Bellator but it's also weak in the UFC.
