11. Browns release Johnny Manziel after two tumultuous seasons

Manziel’s fall from grace—from first-round pick to all-time bust—was officially complete when the Browns parted ways with the troubled quarterback in March. Manziel was unable to curb his partying despite a stint in rehab, and was investigated in January for a domestic violence incident against his ex-girlfriend (prosecutors later agreed to drop the charges). — Amy Parlapiano
