He may have been there already, but Rolando McClain guaranteed himself a spot in the conversation over biggest NFL draft busts on May 15, 2013, when the Ravens announced his retirement. The 23-year-old linebacker out of Alabama registered just a half-sack in his rookie season. Two more subpar years in black and silver (and off-field issues) led the Raiders to release him. In need of some linebacker help, the Ravens picked McClain up in the 2013 offseason. He responded to that reprieve by getting arrested in April, his third run-in with the law in less than a year.
