San Francisco 49ers – A.J. Jenkins
Jenkins arrived in San Francisco as a first-round pick with a big reputation. They drafted him in 2012 after a stunning college career with Illinois. He broke records during his time with the Fighting Illini. But he spent most of his time on the bench during his time as a Niner. Fans expect first-rounders to contribute quickly but he didn’t do anything.
It says a lot that he dropped the only pass that came his way during his rookie season. Jenkins also played in a Super Bowl but didn’t do anything except run around a bit. If they won, he would surely be the worst player with a ring in history. They didn’t lose because of him but it didn’t help that he was useless (via NBC Sports).
