New York Jets quarterback Justin Fields has already made a strong impression on head coach Aaron Glenn. Glenn called Fields' confidence "unshakable" on Saturday, per Zack Rosenblatt of The Athletic.

Aaron Glenn stood on the practice field with his arms crossed, observing. On a windy Saturday afternoon during rookie camp, Glenn was often on the move, bouncing from position group to position group.

New York brought in big-name superstar talent -- like Aaron Rodgers -- and was loud in its approach. That didn't work, though. The first year of Rodgers' stint was impacted by his Achilles injury and then last year just didn't go as planned.
