Joshua Dobbs

Dobbs has appeared in just seven games across his three seasons in the NFL, and he's completed 10 of his 17 passes for 45 yards and an interception. The 2017 fourth-rounder played in Pittsburgh's Week 17 matchup last season, but he'll face an uphill climb to secure a spot on the 53-man roster while competing with Mason Rudolph and Dwayne Haskins in camp.

The 2017 fourth-rounder saw his first regular-season duty last season, but Dobbs remains entrenched as a backup for the Steelers, with Ben Roethlisberger having signed a two-year contract extension during the offseason. Dobbs enters training camp second on the team's depth chart, but for that slotting to stick, he'll have fend off second-year man Mason Rudolph.

Considered the possible quarterback of the future when he was selected in the fourth round of the 2017 draft, Dobbs never saw a regular-season snap for the Steelers as a rookie. Stuck behind Landry Jones, Dobbs now faces additional competition from Mason Rudolph, taken in the third round this year. It seems likely that either Dobbs or Jones will not make the roster coming out of camp this season.

The 6-3, 216 pound QB is a great athlete who also possesses tremendous smarts. As a result, Dobbs has the tools to make for an interesting developmental project behind Ben Roethlisberger. While his downfield accuracy was quite strong by the end of his Tennessee career, Dobbs never showed the natural ability to read defenses that you'd like to see in a quarterback. If his experiment at quarterback doesn't go well, Dobbs has the athleticism to transition to receiver. For now, he's slated for No. 3 QB duties in 2017 behind longtime Roethlisberger and backup Landry Jones, who has served in the Steelers' No. 2 role for each of the past two seasons and was signed to a two-year extension before the NFL draft.
