When a rookie walks into an NFL locker room for the first time, the jersey number on their back isn't always a matter of choice—it's often a matter of circumstance. For the Indianapolis Colts' 2025 draft class, that reality played out in fascinating ways, with some players finding unexpected meaning in the digits they were handed.

The Colts' top two picks, both arriving with high expectations, discovered that even first-round status doesn't guarantee your preferred number. Second-round linebacker CJ Allen, fresh off a standout career at Georgia, had worn No. 3 throughout college. But that number already belonged to Colts kicker Spencer Shrader, leaving Allen to scan the available options.

What he found was No. 53—a number that initially seemed like a simple assignment but quickly revealed deeper significance. "It was the number that was given to me," Allen explained during rookie minicamp. "It just all started making sense—53rd pick. It's a great linebacker number, especially here for sure."

For Colts fans, No. 53 carries weight. It's the number recently worn by Shaquille Leonard, who burst onto the scene as Defensive Rookie of the Year in 2018 and earned three first-team All-Pro selections before a spinal injury cut his Indianapolis tenure short. For a linebacker stepping into those shoes, the number represents both a legacy and a challenge.

Later-round picks faced an even simpler equation: take what's available. With fewer numbers to choose from and less negotiating power, rookies often end up with digits they never imagined wearing. But as Allen's story shows, sometimes the number that finds you ends up fitting better than the one you wanted.

Whether it's a meaningful coincidence like matching your draft slot or a chance to carry on a team tradition, these jersey numbers become part of each player's identity—and a new chapter in Colts history.
