Wow. You must think highly of Shields to think he can even match up against Mousasi.
Lets take a Top 10 Welterweight, who fights at 185 sometimes and match him up against a fighter who has fought at Heavyweight and Light Heavy in his last two fights.
Even if I imagine that they are the same weight when they fight, Mousasi would smash him. Lets see how Shields handles Miller before we go this far.
I don't have favourite fighters, just favourite fights.
