Offensive lineman Trent Williams wasn't one of the flashy potential stars available in this year's draft. He isn't a fast receiver or a 15-sack pass-rusher with his whole career ahead of him.
Yet the 49ers' acquisition of Williams is one of the biggest moves of the entire draft. It's also, easily, one of the best.
The 49ers got Williams from Washington for fifth-round pick this year and a third-rounder next year. That is startlingly little compensation for a player of Williams' caliber. The Dolphins traded offensive lineman Laremy Tunsil to the Texans in a deal that brought them two first-round picks last September.
