Israel's "best" win (meaning best opponent he's beaten) was his last one, a lackluster decision over Vettori. I'd bet Jotko or Theodorou over Vettori at evens, and those are 2 of Brad's last 3 fights (the other being a win over Leites). I mean, does anyone really think Vettori is significantly better than Jotko LOL? And while Israel struggled with Vettori and lost round 3 (even with Vettori clearly tired as hell), Brad pretty much dominated Jotko the entire fight and then put him away.
This fight isn't about Israel's long term potential and eventual ceiling, it's about how good he is now, this Friday night. Based on what we've actually SEEN from both guys in the cage lately, I think it's insanity to pay juice on Israel here. Yeah, he might look better this time and win, but there's no evidence so far to support that. Doesn't mean his long term ceiling isn't higher than Brad's, it just means right now Brad looks like the more well rounded fighter. So at dog odds, it's kind of a no-brainer to me.
