I'm not so sure, I think TJ might take the win there. In my mind I see it as perhaps 60/40 Cody, depending on if TJ has sharpened up a few openings he makes then I'll go 50/50.
What makes it even harder to predict is that they have trained together for so long. Both guys have improved since so it's hard to tell. Also you have TJ doing more boxing sparring (hopefully with Loma or someone skilled again) which might help him prepare for Cody.
Another X factor is that, while Cody has looked strong in his UFC run, I think part of the reason he looked so excellent against Cruz was because of the matchup. Alpha Male has had like, what, 6-7 camps preparing for Cruz? Finally he slowed down a little and they found the guy who could do it. You have to think that they know Cruz better than they know anyone else, and that Cody was prepared as best he could for exactly that. Maybe he overperformed and wont look as good against TJ.
Great fucking fight! Might be the one I'm most looking forward to this year.
