Weidman v Belfort is one I wouldn't want to try to pick at this stage - I'm ashamed to say the only Weidman fights I've actually seen are the two against Silva, and they didn't really give us much to go off. As for Belfort, there's the question of whether he'll be allowed to continue using TRT in the leadup to the fight, and how that will affect him.
Interesting how everyone is already writing off Jones-Teixeira as a Jon Jones win: don't get me wrong, I think he'll win too, but we all though that about the Gustaffson fight too. Just saying...
Aldo-Pettis (assuming the stars align and it actually happens) should be a great fight later this year, as should Hendricks-Lawler for the welterweight belt.
