Mousasi is going to be alot smaller, but I think he has the superior technical prowess, especially in the striking department, however I think they're a bit offset by Goose's size.
I think Mousasi takes this, but if Goose tries to grappling him, it's a tossup. Mousasi's got dope subs, but I think size will really be to Goose's advantage.
Keep in mind I'm a Mousasi mark, but his striking is pinpoint and he'll know be fighting regularly.
