I'm gonna guess that the addition of the smiley means this wasn't technically an insult.
No, my point is that Cap has already beaten Hawkeye. Question asked and answered. If you want reasons as to why Cap would beat Hawkeye, one of those reasons is that he's done it before. Another one of those reasons is that Cap is the physical equivalent of Jason Lee's character from the movie Soldier while Hawkeye is the equivalent of...some dude who shoots arrows. Another one of those reasons is Hawkeye has learned just about all he knows about fighting from Cap...but not all Cap knows.
Now...maybe if instead of a ass-whupping competition, they were having a bow and arrow competition, Hawkeye would probably win that, because that's kinda Hawkeye's thing.
Yeah, and my point is that people have "won" in superhero battles because of popularity. It's because Wolverine suddenly became uber badass or Batman can seemingly beat Superman day in and day out.
So in any Marvel comic, Cap could probably find a way to beat Galactus. It doesn't mean that if we do a Galactus vs. Cap fight that people might not think differently. It's a mental exercise, not a "in issue 362 of Avengers, Cap clearly wiped the floor with all the Avengers therefore he would win against any of them in single combat."
Hell, Black Panther took out the entire team in the animated show single handed.
