Semi tempted on Kattar just cos of the odds. Zalal has looked fantastic since his UFC return but that has been against a much lower tier of fighter. Calvin is coming towards the end of his career and did just get completely grapple fucked by Aljo, but Aljo I think has proven himself to be one of the best grapplers at 145. Zalal could end up earning a similar tag but Calvin has historically had very good takedown defence and Zalal is a huge favourite while there are still questions about just how good his wrestling and grappling is at the highest levels of the division.
Vince Morales is another dog I'm tempted in. Don't really know much about his opponent but the odds are pretty wide given Vince is a solid fighter. He's lost a few in the UFC but in fairness they're all against solid guys, like all of them are against legit competition. Not sure this fella he's fighting is at that level.
