I agree with your point that the loss of velocity decreases the margin for error. However, Pomeranz is never going to blow guys away with a blazing fastball. He will always rely on command rather than velocity. I am confident that he can win a lot of games with his stuff if he can hit the corners-and equally confident that he will lose a lot of games if he cannot command his pitches. The same can be said about a lot of pitchers. Just as a reminder, last year, despite not having a great fastball, he was 17-6 with a 3.32 ERA.
