KT would've bullied Cotto similar to the way Margo did. i.e. keeping Cotto on his back foot while landing shots until Cotto could take no more.
I thought Cotto improved noticably when he moved up to 147. At 140 I would make Kostya a clear favourite. Cotto's defence was never that great and Kostya was one of the most accurate punchers I've ever seen. I doubt Cotto can take his punches for 12 rounds, especially considering he rarely initiates a clinch. Tszyu by stoppage.
most of you already said it, cotto's chin and his leaky defense cant stand up to tzsyu's accuracy. cotto would be running for his life. tzsyu by ko
I think this would have been a pick em fight with maybe a slight edge towards Kostya. The fighters Tszyu defeated likely get beaten by Cotto and vice versa. Tszyu was a great 140 pounder at his peak, but even then he wasn't as untouchable as most would lead you to believe.
Tszyu by KO in about 8-9 rounds. Tszyu was very heavy handed indeed and was a skilled boxer when he wanted. De La Hoya couldn't put a dent in Gonzalez but Tszyu had him hurt multiple times. I can't see how Cotto will deal with that kind of power.
cotto got a suspect chin and tyzu hits really hard only 1 winner for me even know i think cotto is a better fighter
Tsyzu was strong at 140 Cotto wasnt. That being said if Cotto fought smart I think he beats Tszyu. Tsyzu was a bit predictable but a very good pressure fighter. Cottos boxing skills are a bit underated. Tough call and a good fight. I would go with Cotto by decision or Tszyu late round KO.
