Allen was an All-Rookie in 2013 when he eclipsed the 1,000-yard mark and had eight Touchdowns.  Allen had less production in his sophomore campaign, and he was on his way to another great year in 2015 when a kidney injury shut him down halfway through the year.  2016 was even worse for Allen, who suffered a torn ACL in the season opener.  

The Wide Receiver was struggling, but in 2017, he was completely healthy and had his best year to date, with 1,393 yards and six touchdowns.  Allen went to the Pro Bowl and was named the Comeback Player of the Year by both the AP and the PFWA.  In the two years that followed, Allen was inches shy of 1,200 Yards and was a Pro Bowler in both years.  He secured his fourth consecutive Pro Bowl in 2020, where he was eight Yards shy of 1,000.  The Wide Receiver remained strong in 2021, adding a fifth Pro Bowl, and had his sixth Pro Bowl in 2023, a year where he had 1,243 Receiving Yards, his second best for the Bolts.

Following the 2023 season, Allen was traded to the Chicago Bears.  He accumulated 10,590 Receiving Yards with 59 Touchdowns for the Bolts.
