Not sure where the term Clemson curve comes from but I think that it has something to do with the way they teach it at Clemson. Coach attended some of Clemsons camps back a few years ago when his sons were in HS and thats just what he calls my sons curveball. Coach has one son that pitches in minor leagues that is home for winter and has been watching my son pitch and he's very impressed with his curveball, and has even tweaked his mechanics a bit, more about pulling down with elbow to take stress off arm. I am trusting that they know better than I about pitching mechanics. Might have to learn how to send a video of this to the pitching thread for so more insight, just really inexperienced at tech stuff.
