I feel like Cintron would be the way bigger guy. But still, Thurman hits hard, no doubt. On the other hand, Thurman's strength as a counter-puncher doesn't necessarily exploit Cintron's weakness against pressure. I go with Cintron.
Nah, Thurman beats Cintron. However, I do see it being a struggle, and I could see Cintron hurting Thurman a few times. In the end, however, Thurman just has more substance. That's more an indictment against Cintron than a compliment to Thurman, as Keith ain't exactly Holyfield in the intangibles department. But Thurman's heart is more likely to hold up in a war than Cintron's is. I'd say Thurman TKO 10 in a good scrap.
