Zac Thornton
Zac Thornton's production (63) outpaces the tools grade (32) by 31 points. Primary finding: existing changeup is present, but its movement shape does not currently cover the desired arsenal-shape:-armside-drop window. Most actionable fix: reshape existing changeup to add arsenal shape: armside drop rather than developing a new pitch from scratch.
