I don't think Cowdell gave Sal too many problems. He just fought to the level of his opponent and people were surprised that Cowdell was still in there after 8 rounds.
I can't see Bernard Taylor, slick as he was, beating Sanchez. Sooner or later Sanchez will catch up with Taylor and punish him to the body to slow him down for those choice right hands late in the fight.
One of Sanchez' greatest assets was his temperemant in the ring - the man was too cool for school.
