Hey look, he's impressive.
So was Stephen Strasburg.
I have no doubt he can be effective now, and even for the next few years.
Hopefully he won't suffer major injury.
Raw velocity is not nearly as important for pitchers as changing speeds.
Pedro Martinez was great, not because he could throw 97. He had it when he needed it. But it was the 94mph heater with the 80mph change. Or the 76 mph curve. That's what pitching should be. Unfortunately in the last 10 years we've seen this crazy emphasis on throwing as hard as you can for 5 innings, then burning out.
Flame throwers like this almost never last. I'm skeptical.
