David DeCastro, OG, Pittsburgh Steelers!!!
What he brings: If you draft a guard this early, you expect him to make an immediate impact, and DeCastro's more than capable of doing it. He's a smart football player who can drive defenders off the ball as a run-blocker and rarely loses one-on-one.
How he fits: Offensive line was the biggest need for this team and DeCastro plays like he was born to be a Pittsburgh Steeler. He can line up next to their only stable lineman, Maurkice Pouncey, and that should really improve their interior run game and also pass protect for Big Ben inside. There's still work to be done on the edge of this offensive line, but this is a major upgrade.
