One difference between Israel and Whittaker/Strickland is his kicking game. To try to just box against someone who is kicking and punching you is a very cardio-intensive way of fighting. I could see a scenario where Izzy kicks a lot to the legs and body of DDP, and uses teeps to control range (like Strickland did a little early in their fight) rather than fighting going backwards. I don't think DDP can check the kicks the way Strickland was able to. IMO, Strickland probably should have gotten the win over DDP with R1, R2, and R5 (although it was close). One factor that bears thought is the size difference. Strickland is built heavier than Israel, and DDP was significantly bigger than him. Israel tends to fight with his hands at chest level, relying on speed, movement, and the threat of the counter for defence. I think he's lost a step now that he's 35, and DDP could catch him and even finish him like Strickland almost did in the first round. I have lots of thoughts, but no clear read.
We haven't really talked about Erceg-KKF. Are we expecting Erceg to grapple him? Can KKF out-strike Erceg?
Considering Hooker as a dog. The judging criteria values damage over aggression and control. Hooker seems like he is more capable of damaging Gamrot than the other way around, even if he spends a significant amount of time fending off grappling. Pretty much the same reason I think Tafa beats Walker.
