Will Mosley be the toughest opponent Mayweather has ever faced?

Will he?

Also,

Will Mayweather struggle the most he has ever struggled? (This isn't the question for the poll).

I actually think the opposite. Shane will want to quit in this fight and Floyd will beat him merciless.

Remember that look he had on his face in the corner during the Winky fights?

[MurderDeathKill]

No. Castillo is.

Too much speed, too much talent. After Floyd gets done with him, Mosley going to be sore for years. So what if its not by KO, but Floyd will make sure that Mosley remembers the beating he gets for years to come. I bet you Jeff Lacy has Nightmares after getting his ass kicked real bad. Don't worry Jeff, Mosley is going to be sharing those same Nightmares after what Floyd does to him.

I cant get the look of frustration that he had against Winky out of my head. He looked like he wanted to quit anyone who seen that fight will tell you that.

Im not saying he will quit but he will look just like how he did when he fought winky and his head was down in the corner.

No. Castillo is.

Same here, I don't think Mosley will give him that sort of trouble.

Will he?

On May 1st,

Will Mayweather strggle the most he has ever struggled?

The only other fighter he has faced recently with comparable speed was Judah and he gave Mayweather lots of problems. Mosley will not fade after 6rds and is mentally much tougher than Zab.

That said im still going Floyd.
