I think TS assumes Conor will just head hunt the whole time and not go to the body or legs. As Conor showed after Nate humbled him, he can game plan for the full 5 with no problem. If Conor starts going to the body, that could totally pay dividends in the long run, with Khabib being totally sapped.
Khabib is also like Conor, in the sense that he is a monster for 10 minutes but then dips. Al was not the first fight where Khabib looked to be str8 maulin' a guy and then he stopped being so dominant. I just do not see Khabib surrendering pressure rounds, hoping Conor will gas and that he can withstand the punishment handed out.
