Made a thread about specific techniques he might use if interested:
How Gus can beat Jones, a study of the first fight (w/ GIFs)
But basically I think obviously use his boxing, but some key methods from boxing he might use are:
- Learn to circle to his left while entering, this would help him avoid both the left elbow and right spinning elbow.
- Double jab to body and head (while circling left) worked well in first fight.
- Throw a right hook to the body after the jab rather than always a right cross, Jon is open to this while in orthodox because he backs away with left arm outstretched leaving the left side of his body open; also circle left while doing this to avoid Jon's outstretched left hand.
- Use jab-left hook while circling left to enter when Jon is in orthodox instead of just relying on entering with the jab-cross; Jon's standard defense to back away while circling to his right while in orthodox is great for evading the cross but puts him in the way of the left hook.
- When Jon is in southpaw, he is more open to entering with the jab-cross since his lead shoulder no longer covers him, but use footwork that covers a lot of distance when throwing it because Jon still responds by backing up a lot.
- Play the same eye poke game as Jon, which is to put your hand right in his face every time he approaches; since no one else will enforce the rules he has to create parity in the rules himself.
I think I would also add:
- Use the collar tie while uppercutting from the clinch, both because Jon could not take him down from the clinch in the first fight, and Jon was very well trained to avoid the uppercut in the first fight (which Gus is known for) except when Gus had the collar tie, Jon also showed a vulnerability to this with Cormier and the collar tie should be easier for Gus since he's much taller.
- Learn to kick while being evasive a lot more. Gus actually succeeded in most of his kicks from distance in the first fight, at least he was rarely countered. He was rarely countered probably because of the distance he can kick from and also because Jon did not trust his boxing against him. But he rarely kicked except when Jon kicked him. So use it a lot more to score points if nothing else.
- Others suggested finishing combos on a kick. I think this is a good idea, but it is unlikely that Gus can implement it because it would require too much of a change of his style from boxing to kickboxing.
