If you're judging rookies only, the choice would come down to kicker Justin Tucker or right tackle Kelechi Osemele. However, in terms of guys added since last season, nobody made a bigger impact than Jacoby Jones. Signed by the Ravens after he was let go by the Texans, the speedy wide receiver was the NFL's most explosive returner this season. He set a franchise record with three return touchdowns, two of which figured prominently in wins against the Steelers and Dallas Cowboys.
