I think Izzy still has it on the feet, may have lost a step, sure, but he can finish pretty much anyone in the division on any given day. If it goes the ground though he seems to lose a lot of confidence and just burns a ton of energy trying to not let it get finished there. Plenty of great fights to make still. There's been plenty of guys with his kind of talent that has lasted a few more years at a high level. I tend to forget how big Izzy is at 6'4" too. Usually, Pyfer makes other middleweights look small, but he and Izzy were about the same size.
Apex card this weekend is meh. The card the next weekend however headlined by Jiri and Ulberg looks pretty damn good top to bottom.
