Influenced by impressive combine results, the St. Louis Rams took Baylor OT Jason Smith with the #2 overall pick in the 2009 NFL Draft. Despite high expectations, Smith ended his four-year career as the least productive offensive lineman ever taken with a top 5 overall pick. While he seemingly deserves to be labeled a Top 10 Bust, his lack of production can be attributed to a history of serious head injuries. In particular, he suffered two season-ending concussions during his first three years in the league. Smith recovered from the first one, but never started again after the second. It's uncertain how good he might have been without the injuries, but it's unfair to label him as an all-time bust because of them.
