Great match-up! I go with Paret to get a decision as he was just so damn busy. Talk about perpetual motion - his fights against Gaspar Ortega, Federico Thompson, Charley Scott & Emile Griffith are some of the most action-packed fights I've witnessed. I don't see Turner knocking Benny out as he had an amazing chin (unfortunately it allowed him to take too much punishment in the end), so unless Turner is willing to go toe-to-toe and back Paret up then he gets outpointed. This would've been a great fight no question.
And that's exactly what he would do. This is one of those fights that will depend more so on the judges than the two fighters. Both will go to war and land their share of punches, although I do get the feeling that Turner might be better off in a fight like this, as he was able to take his campaign even up to middleweight while Paret was only in for a beating against the likes of Fullmer.
