This fight is actually more appealing to me than Silva/Cote was, and that's because Thales poses a legitimate threat on the ground, which we haven't seen Silva deal with since his fight with Lutter.
What it boils down to, is how Silva approaches the fight. Is he going to destroy Leites on the feet? Or is he going to play the ground game with him, and avenge another submission loss for Pele (which he did with Lutter)?
Leites takedowns aren't great, but he's a very tough guy, so he needs to work on setting-up his shots with strikes, or else he'll be eating leather for as long as Anderson wants him to be awake.
