Spoiler Thread: Avengers Infinity War

Possibly, but with Hulk, he didnt use the power stone and took that fight seriously. He was focused, brutal, and did what he could to wear down / disable Hulk fast.

My point is with Cap he never even dropped into any kind of a fighting stance. He didnt take him that seriously. Maybe he underestimates him, sure, but he still didnt have to try hard to knock him back.
I understand your point. I never thought Thanos considered he was in much danger. I was saying Thanos was not "toying" with Cap.
