In the old world of college football, you had 85 scholarships. Every single one was precious, often forcing coaches to make impossible choices between a "project" player with high upside and a transfer who could play right now.
In the new world, with the NCAA moving to a 105-player roster limit, the game has changed. The scholarship cap is effectively gone (replaced by the roster cap), which means those "developmental" guys who weren't seen as roster-worthy before can now be signed, scholarship'd, and developed in your system.
Will Stein clearly understands the assignment. His last two additions aren't just depth pieces; they are proof that Kentucky is embracing the sign and develop model.
