The primary basis for inclusion in the latest edition of the ESPN Jr 300 was in-season production. Our scouting staff reviewed over 1,000 prospects in the class of 2017 throughout the last several months -- both in person and through HUDL film review. While we cross-checked every prospect already included in the Junior 300, we also scouted a plethora of prospects outside of the group. A lucky 13 players enter the elite fraternity in this edition, in an update that also sees some big risers up front -- and behind center.
