On the feet.
Walker has more variety.
They both hit hard.
You'd have to bet on Crute having the better chin, though it hasn't been tested he is 24 and not taken much damage before.
Crute will try to pressure on the feet, take the space away from Walker, Walker will try to dance around on the outside and stay long.
On the ground.
Crute dominates him in wrestling, BJJ and physical strength.
There is a chance Walker catches Crute with something big, but I think he has one round to do it. The more likely outcome to me is that Crute pressures Walker for 3-4 minutes, and if he hasn't got the KO Walker has already slowed enough for Crute to push him against the cage, drag him down and soften him up with some ground and pound, repeating until Walker gives him a neck or arm.
Crute by round 2 sub.
