The writing was on the wall for Zach Mettenberger as soon as the Steelers grabbed another quarterback in the draft.
After selecting Tennessee's Joshua Dobbs in the fourth round this past weekend, Pittsburgh on Monday released Mettenberger, the fourth-year passer who has now been cut by three NFL teams.
Tennessee, at one stage, saw Mettenberger as a potential quarterback of the future, but the question now is whether he'll ever have another chance to start at the pro level.
Quarterbacks have nine lives in the NFL, but few young passers have seen their stock tumble as rapidly as Mettenberger, who is no sure bet to make a roster next season.
