It takes a lot of courage to post this type of eval question. I commend you for that. My first question is this: Are you a LHP or RHP? Big difference. I searched through your posts but couldn't figure it out. If I missed something here just disregard my reply. But there is a big difference. Lefty rising senior currently topping at 79mph kinda could project. might pick up 2-3 mph with just a few mechanical changes ( Stride length ) and arm strength ( Long toss). Now its a rising senior lefty topping out at 82-83. That works with movement and a nice curveball.
But with a righty, It's a different challenge. If your numbers are on the right side, same thing. Try to pick up 2-3 mph w/ adjustments but you will see less interest.
Soft tossing leftys play NCAA baseball. Rightys not so much
