Murray probably stops Thaxton, but I don't rule out the possibility that Murray may get stopped before the 6th round.
If Murray can take Thaxton's shots he would win as Jono tires - Murray seems to have the stamina to make him fight three mins of each round, which is bad news. Murray's chin is largely untested, he is nearly 30-0 but against what exactly, a distinct lack of punchers me thinks. Hennessy needs to keep him active against good oppo, rather than six month breaks all the time.
