In all seriousness I think that fight played out as it should. Cap did not know this opponent of what level threat he posed. Cap could see he was more than just an average dude right away. So Cap is going to spar with the guy a little while seeing what he can do and getting his timing down and then dispatch him quickly once he knows. Next time they meet Cap should be expected to just walk thru him as he now knows the level of threat he poses.
