Over on Agents of SHIELD, we see an Asgardian commoner casually catch a knife blade with his bare hand and bend the knife, and then easily break out of handcuffs. In another episode, we see Lorelei casually punch a dude so he goes flying several meters, and Sif kick a pretty big mobile home across a parking lot in order to provide cover. I don't know where Lorelei and Sif rank on the Asgardian power level scale, but I'm pretty sure they're nowhere near the top.The Asgardian gods are supposed to be that strong. The Asgardian commoners are a bit stronger on average than humans.
And in Avengers, Loki doesn't really have any trouble kicking America's ass until Iron Man shows up. And I'm pretty sure Captain America is supposed to be a significantly better fighter than TVA no-names and random train guards.
