Allen was selected in the fifth round by the Falcons in the 2014 draft out of Purdue. The former Boilermaker started off his NFL career as a cornerback for the team and spent his first season with Atlanta on the practice squad. In 2015, Head Coach Dan Quinn switched Allen over to safety and since then he has played in 47 games with 46 starts over the last three seasons and has recorded 212 tackles, one sack, six interceptions, one forced fumble, and nine passes defensed.
Last season, Allen took a step as one of the vocal leaders of the defense. He posted 54 tackles (38 solo) with one interception, one tackle for loss, and one pass defense while starting 15 games at safety. His leadership on the defensive side of the ball helped the team become the first Falcons defense since the 1998 squad to finish the season ranked in the top 10 in total defense and scoring defense.
