Well this all depends on the answer to this question .....

HOW MUCH RESPECT DOES FLOYD WANT?

If he wants to be recognized as "The Greatest Fighter of All-Time" then he has a TON of work to do at 147-154 and maybe even 160 and yeah I think he could fight there vs some smaller or slower guys.

...if he just wants to be one of the greats then he's pretty set right now but could really solidify his place in history by once and for all UNIFYING A DIVISION.
