Hackenberg was benched for former LSU quarterback Zach Mettenberger. That could be the last time we hear of Hackenberg.
Hamburger jokes aside, getting benched in the AAF after already being a failure in the NFL shows that Hackenberg has been overcooked (couldn't resist). The former Penn State quarterback has never lived up to the expectations he was given coming out of high school as a top prospect, and it's really a shame considering how great many thought he could be.
At one point during his time in Happy Valley, Hackenberg was an early projection to be the No. 1 pick in the NFL Draft, which goes to show just how much time has passed since then. He wound up being drafted in the second round by the Jets, but never did anything meaningful in the NFL.
There will most likely be a sports broadcasting gig at the Big Ten Network waiting for Hackenberg when he catches up with the rest of us in realizing that his playing days are over.
