Stroud had some nice completions, particularly to Collins. But his accuracy, which is a strong aspect of his game, was gone on many plays when under pressure. He had some really bad throws to go with his good ones. The commentators also mentioned he failed to see/find open receivers on several plays. I don't have all 22 so can't confirm, but at one point in the game I felt he was flustered by the pressure. I haven't rewatched the game, and Stroud had some good pocket moves on several plays, but there were other plays his pocket presence was not so good.
I would say, based on just one game, jury is still out.
