I don't see how cap is looking at an L, who on Tony's team is really that intimidating other than Vision?
Who will most likely not even attack anyone... Because he's vision.
If you guys really think Spiderman is really going to be that featured in the movie/that skillful already I have some bad news.
Iron Man and War Machine alone can take out Cap's entire team, with Scarlet Witch again being the outlier. Hawkeye and Falcon are the two weakest links though, with Falcon especially relying on easily damaged flying gear, that isn't easily replaceable. Snipe him in the sky and he's altogether out of the fight. And then you could say the same for Natasha on the opposing side, but in terms of hand to hand combat she's superior to both Clint and Falcon, and with her own weapons is about even. Spider-Man's something of a noob, so he could be a weak link, but not in terms of his actual abilities, just experience. Ability wise, he's also capable of taking down a good chunk of Team Cap. If Vision appears in the film outside a cameo he's going to fight people, especially if they're attacking him. And in that case he's also soloing most of that team. Though I honestly imagine he and Scarlet Witch will cancal eachother out for some kind of romance subplot.
