BIOGRAPHY: Former fullback who moved to tight end after his junior season. All-Conference selection last year after totaling 42/426/1.
POSITIVES: Athletic prospect who has displayed skill handling the ball. Plays with leverage, quickly releases into pass routes and is a solid receiver. Strong at the point, blocks with good fundamentals and nicely works his hands as a blocker or pass-catcher.
NEGATIVES: Not physical and never consistently attacks blocking assignments. Does not finish, and falls off blocks. Marginal speed.
ANALYSIS: A former fullback with no position in Oregon's new offensive system, Rosario has been out of place at tight end. Could have a home as a lead blocker in a West Coast offense if he picks up the physical nature of his game.
