I actually think Fiziev will target the body a lot here, Gaethje keeps a pretty high guard which leaves his body to be pretty open.
Most of his opponents are head hunters(Dustin, Chandler, Johnson, Eddie), but even someone like Eddie had some good success to the body which help lead to a finish.
Fiziev goes for the body, legs and head, the dude has a ton of variety in his attacks which is something we Gaethje hasn't really faced before.
I do agree with some that Gaethje is being a bit underestimated here and I see him making this a hard fight due to his volume and counters, however I'm predicting Fiziev will get a late finish after many brutal exchanges between him and Gaethje.
