I wouldn't write Harris off so quickly. He hits like a train and is one of the more athletic heavys on the roster.
Shamil got knackered and TKO'd by Tim Johnson who while being big and strong, isn't brilliant at anything. He's just a big strong HW with decent TDD.
If Harris can keep this standing, he'll put Shamil away. But Shamil did look much improved especially cardio-wise against Hamilton (for the record, Harris would KO Hamilton - IIRC, he already has in his career but I maybe thinking of someone else).
Fuck it, I'll go against the grain and go for Harris, TKO, 2nd round.
