I don't think Creed showed enough in Origins to beat Cap. He had skill and some decent durability, but certainly less strength than Cap and IMO he's doing to have a hard time getting a hit past the shield (which took a Thor strike)

Well Imo Creed is more agile (school scene taking down Cyclops or he easily climbed the side of that huge building in the begining of the movie) and he was easily throwing around Wolverine like a ragdoll before the "upgrade".
He's agile, sure, but I think he's slower than Cap which makes it difficult for him to put that agility to use. He can jump around all he wants, but when he goes for a strike I think Cap's gonna block it.

Didn't he lift a tree again or a telephone pole in his fight with Bone Claw Logan? Can't remember either now, maybe I'm confusing things with the video game.
