Round, 6: Dallas Lewallen

The Raiders now have a one of the biggest offensive lines in the NFL but need some depth on it. And 6’6″, 322-pound Dallas Lewallen is the perfect lineman to bring in here in the sixth round. That’s because when you draft for depth on the offensive line, versatility is what you should look for.

You just never know where you’ll have an injury so you need a backup that can play multiple positions. Lewallen would have the center and the guard positions covered if the Raiders brought him in. After spending a lot of time at center last year, Lewallen played every game at guard in 2014.
