For Ty Montgomery, embracing a full-time switch to running back wasn't about carving out a longer career -- just a more productive one.

Drafted by the Packers in 2015 as a receiver, the 6-foot, 216-pound backfield convert recently explained his thinking:

"Do I want to play in the NFL for a longer period of time and not be as happy because I'm not having the amount of success that I'd like to have?" Montgomery said Tuesday on ESPN, per Rob Demovsky. "And if running back gives me that, then I'd rather play [6 to 8] years in the league ... having a successful career and having a lot of fun doing it and not always battling to be somebody's fourth, fifth or sixth receiver, even if it meant a [10 to 12-] year career."

Montgomery served as a fascinating case study last season, entering camp struggling for snaps as a pass-catcher only to emerge by midseason as a reliable helper in Green Bay's ultra-banged-up backfield.
