I don't know about you guys but for some reason I could easily see it as a sort of modern day Hearns-Duran fight. A short and aggressive offensive juggernaut against a tall natural 147+ fighter. It didn't end too well for Duran in that fight. Even though it was fought at 154 and Manny has better mobility than Duran, the fight with Williams at 147 would still pose too many physical problems for Manny, imo.
