He's getting first-team snaps as a slot receiver, catching touchdown passes and drawing pass interference penalties.
Bealsey left the team for two days for personal reasons but returned focused.
Coach Jason Garrett has noticed.
"Players need to regain their perspective on where they are," Garrett said. "One of the things we liked about Cole Beasley coming out of school was his love of the game, his passion for the game, his willingness to work at it, and that's just how he's always played. It showed up on tape in college and it showed up around us in the spring, so by having to leave, we just had to try and help him regain his perspective, and when he came back he was the guy that we knew."
