Daryll Clark, the more experienced and agile quarterback was being weighed against the younger, more prolific passing threat in Devlin.

In the end, Penn State coach Joe Paterno chose to start Clark, while having him split as much time with Devlin as would be possible.

[3] When Clark was forced out in the fourth quarter of the Nittany Lions' crucial game against Ohio State due to a concussion, Devlin led the team on a go-ahead drive that was culminated by his own 1-yard touchdown run.

[7] Devlin started all eleven games for the Blue Hens, passing for 2,664 yards, sixteen touchdowns, and nine interceptions.

[8] In the final game of the season against Villanova, Devlin passed for Delaware school records in completions (42) and attempts (58) and threw for 407 yards.

[11] He also was honored as the Eastern College Athletic Conference Division I – Championship Subdivision Offensive Player of the Week.

[12] The Sports Network wrote that "Devlin has put some teeth back into the Blue Hen passing attack with his accurate throws and on-field leadership",[13] and included him as a finalist in the voting for the 2009 Walter Payton Award,[14] given to the most outstanding offensive player in the Division I Football Championship Subdivision (formerly Division I-AA).

Back at home against Maine, Devlin completed 20 of 36 passes for 286 yards, leading the Blue Hens to their sixth win of the season.

After a close win against Rhode Island and a one-point loss against William & Mary, he dominated against Towson, completing 29 of 38 passes for 318 yards and one touchdown while running for another score.

[35] During the Dolphins' 2014 preseason, Devlin injured his hamstring, and on August 11, 2014, he was waived in favor of signing Brady Quinn.

[42] On December 31, 2015, Devlin was re-signed by the Browns to be back-up to Austin Davis, after it was determined Johnny Manziel would not play due to his status in the NFL concussion protocol.

[43] He was not re-signed by the Browns going into the 2016 season, as the franchise moved on from Manziel and brought in Robert Griffin III as their preferred starting quarterback.
