X: 2014 - First round OT Greg Robinson (2nd overall)
It's almost impossible to imagine that a player who was selected as the second overall pick from the 2014 NFL Draft did not even manage to play out his rookie career with the Rams, but that is the history of offensive tackle Greg Robinson. Standing 6-foot-5 and weighing 332 pounds, this former Auburn Tiget offensive lineman was the talk of the 2014 NFL Combine, a true workout warrior who was able to raise eyebrows with his athleticism.
He was a bit raw, but his size and power wooed NFL analysts into a consensus that he was the real deal in terms of becoming a franchise left tackle for the Saint Louis Rams. He never lived up to that projection, and after three difficult seasons, the team finally traded him to the Detroit Lions for a 2018 sixth-round draft pick. Not all drafted prospects succeed, and Greg Robinson is a prime example of that.
IX: 2009 - First round OT Jason Smith (2nd overall)
The Saint Louis Rams have not had much success when drafting offensive linemen in the first round of an NFL Draft. In 2009, the team also spent the second overall pick on an offensive tackle, this time Jason Smith out of Baylor University. Smith was a 6-foot-4 305-pound offensive lineman, and held all of the promise of a highly coveted offensive lineman. Curiously, he did not play left tackle but slid in to play right tackle for the Rams.
He struggled to live up to his drafted slot, and then suffered a devastating head and neck in a 2011 game against the Dallas Cowboys. He was chosen as the successor to Rams legendary offensive tackle Orlando Pace, but never lived up to that role. After three seasons with the LA Rams, he was traded to the New York Jets for OT Wayne Hunter. Smith is now a football coach in Texas, but his NFL career lasted just four seasons.
