Eveyone's physiology is different, some guys can throw long toss all day every day (Nolan, Maddux, whoever), some guys need to be babied. Some guys put so much torque on their elbow I don't understand how they don't blow it out within 20 pitches. If you could figure out the formula for time vs use vs age, you could literally make a hundred million dollars.
Very concerned about McCullers. After throwing his career-high innings, he's injured (twice) to begin the following season.
