Rosario nabbed two passes for 15 yards in Sunday's loss to the Dolphins, but fumbled the ball away after one of his catches. It's not often that Rosario's production exceeds that of Alshon Jeffery (two catches, nine yards), but that's exactly what happened Sunday. That probably is more of an indictment of the Bears' offense than an endorsement of Rosario, who brings his greatest utility as a blocker.
