25. Christian Hackenberg

Granted, New York Jets General Manager Mike Maccagnan badly overrated, and ludicrously reached for, Hackenberg. Regardless, as the 51st pick in 2016, it’s astounding that the 6-foot-4, 230-pound Hackenberg never took a single snap for the Jets.
Gang Green’s hierarchy acknowledged their error on May 22 and sent Hackenberg to the Oakland Raiders in exchange for a conditional 2019 seventh-round selection. Approximately three weeks later, Hackenberg was cut by the Raiders. The 23-year-old Hackenberg is a free agent without any known suitors.

24. Johnny Manziel

Manziel would have been rated higher on this list just one year ago. Fortunately, the 25-year-old Manziel has sought help for his host of problems and he’s seemingly on the upswing as a member of the CFL’s Hamilton Tiger-Cats. Still, as the man who the Cleveland Browns took with the 22nd pick in 2014, the 5-foot-11, 210-pound Manziel remains a notorious bust.
“Johnny Football,” who completed 57 percent of his attempts for seven touchdowns and 1,675 yards in 14 games as a Brown, was cut by the inept franchise in March 2016. Manziel’s work ethic has been praised by his coaches north of the border and a return to the NFL is seemingly inevitable.
