The Winter Soldier movie is basically where he received his amp. I think we can apply Civil War to this.
If we look closely at this scene, Steve actually had time to react to the kick and was braced with his shield and Batroc still sends Steve a good distance back, twice.
Look at the level of skill, speed and durability he shows in this scene to last this long against a shielded Steve.
Even in this scene (yes he lost), he still showcased great durability to tank multiple hits. He awakens pretty quickly after being knocked out by Steve too.
Compared to other combatants, look at how effortless it is for Steve to take out Rumlow. But Rumlow did much better against him in Civil War, because of his stat boost with the new suit. What if stats were equalized in the Batroc vs Steve fight, because we know how good Steves physicals are. The fight was already pretty long enough.
I think theres no problem placing him around just above Widow/Season 2 Green Arrow or White Canary
Oliver and Sara against a weaker Super Soldier, dismantled very quickly.
Widow against Bucky (IIRC people who worked on the movie said Steve and Bucky are equals) with some support as well. Dismantled very quickly
If anyone else has anything to add, you're more than welcome.
