If Tony can give The Hulk the work then he can easily take down two roided super heroes.
Ummmm it wasnt easily and he had to were this bulky super suit on top of his super suit. Not to mention lets be real breh.... Hulk isnt a skilled fighter or trained soldier, he's just a strong angry brawler.
Cap taking on practically 2 best of the best soldiers... SUPER SOLDIERS, and what they lack in power, they more than make up in with tact, speed, and agility (Hulk aint fast either) Look at them combos. They was hittin Stark with like 6 attacks in the same amount of time it would take Hulk to throw one single punch
