Dennis Quaid has to be..
..one of the worst actors of all time.
I've played some ball (and continue playing slow pitch softball at 55), and I can tell you that when you can pop the ball the way Jim Morris did, you know it. Quaid always had a look on his face (bordering on confusion) that he didn't understand how hard he was throwing. When he was throwing to the high school kids, or at the major league tryout, he looked like the last person on Earth who knew he had some steam.
Good movie, but that really grates on my nerves.
