Aaron Donald is the single best football player in the NFL who doesn't play quarterback. He's unstoppable. If you don't double-team him, you die. And even when you do throw multiple blockers in his path, he still generally gets where he wants to go. Donald blows up offensive lines and wrecks plays. He sacked the quarterback 20.5 times last year, and I still don't think that number -- which is insane for an interior D-lineman -- does justice to his domination. The guy's been in the NFL for five years. In that time, he's earned five Pro Bowl nods and four first-team All-Pros. He was named Defensive Rookie of the Year in his debut season and has taken home Defensive Player of the Year honors in each of the past two campaigns. Remember when people worried about the Pitt product being undersized in the pre-draft process? Yeah ... not so much. Aaron Donald makes the Rams' D.
