Mosley relies on his footspeed to get him in and out. He tends to pull straight back a lot and sometimes hes fast enough to get out of the way but I never considered him a very good defensive fighter. Cotto has a better defence but when hes hurt its usually his offence that gets him out of trouble. Hes not a bad defensive fighter, but hes not a wizard. Neither is Clottey but he always has a tight guard and getting through his guard is no easy task. He his open for wide punches around his guard, which is his biggest defensive flaw.
