After seeing the airport fight...clint odds are quite better. We dont see how but during the his melee with Panther, he manages to not only get close, but has him at an advantage (briefly). He is behind him, and has his bow to his throat. Again this is after already engaging him. Black panther was earlier shown to be a match for cap strength and speed wise and nearly killed bucky. The fact that clint engaged him in close quarters and manage to somehow get him in a disadvantage position like that...oh yea Clint has much much better odds. He had some nice agility feats during the airport fight as well.
