Tyson is a great historian of boxing, but people tend to put too much stock into the predictions of those involved in the business.

For instance, I remember a HBO broadcast where the great Manny Stewart predicted that Sharmba Mitchell would be too much for Floyd Mayweather.

I didn't see where Tyson picked Pac, I just see that Tyson thinks Pac is more exciting to watch, which I think almost everyone would agree to.

Also like mentioned above, it's one thing to look fast against someone as slow of hand, foot and mind as Rios. Floyd is in a different league.
