So far, the best rookie from this year's Ravens draft class has been guard/tackle Kelechi Osemele, the second-round pick out of Iowa State. He may not be starting now, but he will be soon, possibly in the season opener against the Cincinnati Bengals.
Yes, Osemele is that good. He has great size, foot speed and athleticism. For a young player, he has shown poise and experience in learning the game and picking up blitzes. Plus, he has those long arms, which allows him to keep defensive linemen away from his body.
