williams would spank clottey. i don't know about cintron. i find cintron a little bit overated on esb. i find him mentally weak, and fights scared even when he's winning like the angulo fight. he boxed well, but there were times he still looked very uncomfortable. i also heard on the day of the first margarito fight, he just locked himself in a room all day, where as margarito, went on about his day, and at night just went to work. this is from teddy atlas so i don't know how true it is.
Williams will probably beat Clottey pretty handily since his workrate is very high and Clottey will spend most of his time putting up his high guard instead of throwing. Clottey would break down Cintron when Cintron realize his power won't dent Clottey. Cintron gets desperate when he can't hurt his opponent and start crying like the *** he is.
