I think Bader doesn't have the mental fortitude to beat any "super star" level fighter, even one that's on the end of their career.
Every time Bader of faced a champion level fighter, he has fallen. He knows he isn't of their level, and he breaks.
Fedor will be no different.
Bader will look pale and shook in the walkout, and he'll eat bombs on any punching exchange he enters.
If he shoots, fedor will toss him like a bag of potatoes and it will be the beginning of the end, as he realizes that he has zero options to beat this man.
Now granted, I will admit that if he comes in sharp and un fazed by the glory of Fedor, it is possible that he could get him down and wrassle him for eternity, but Fedor has shown in his last couple fights that he's still got those hips, so I just don't feel like it will happen.
Fedor inside the distance, likely under 1.5.
