I'd say around top 3. Cotto was ranked #1 by most boxing outlets, and his performance last night IMO shouldn't really hurt his standing TOO badly, maybe bump him down to #3 and put Canelo or Floyd #1 and #2, however you want to rank them. Thoughts?
Floyd was arguably the best fighter at 154lbs already, and then he "beat the man" last night. Why would he not be Number One?
