Izzy is a good fighter, but he brought into his own hype. Jan isn’t spectacular, but he’s a big LHW with solid striking and big reach.
I was surprised how effective Jan’s jab was against Izzy. Israel has huge reach for a MW, but clearly isn’t used to not being able to strike safely from range.
And once the wrestling started, he struggled even more. Izzy learnt there’s a reason for weight classes. He needed to bulk up more, and learn to fight without a huge reach advantage.
