One of the most overrated factors we all talk about is fastball speed. Far more important are location, movement, and especially ability for the hitter to pick it up. Watch Woodruff and Peralra and you'll see what I'm talking about. Woodruff is, for lack of a better word, hittable. When he lacates, he's tough. He has a big fb, but doesn't seem to "play" that fast. Peralta, on the other hand, is harder to pick up and it's just on you. Much like Hader. You would think they're throwing 98. Not giving up on Woodruff, I think he needs to throw more off speed stuff to have success at the MLB level.
