18. San Diego Chargers (9-7), Aldon Smith, DE/OLB, Missouri: The Chargers wouldn’t flinch if Smith’s still on the board. Though he played just two years at Missouri and missed some of his sophomore season with a broken leg, Smith was a high-impact player when he was actually on the field. In 2009, his freshman year, he recorded 19 tackles for a loss and 11.5 sacks. Smith would be a wonderful addition to an already stout Chargers defense.
