Trevor Davis is entering a contract year.
Of course, had Davis been on the heels of a season that he played in all 16 games -- much like his 2017 campaign -- then he would likely be a no-brainer to retain. However, a nagging hamstring injury caused Davis' third season in the league to culminate on injured reserve.
But when he's healthy and capable, there's little doubt that Davis is the best return man on the Packers' roster, regardless of how difficult that is for some to admit. While Davis has never been flashy or consistently impacted games on a weekly basis, even the slightest shift in field position by a serviceable return man could be momentous for the offense.
