To say that Cobb burst onto the scene in his first NFL game would be a massive understatement. His kickoff return for a touchdown was as nice of a return that you will ever see. And he was an obvious factor with the offense.
Cobb is the only rookie in the Top 10 who was not drafted in the first round. Though I'm not sure why RB Mark Ingram is in at No. 4. He didn't do too much against the Packers on Thursday night.
