Once again, the Lions are adjusting at running back. In Week Seven, Maurice Morris was to get the start vs. Atlanta with Keiland Williams the backup after Jahvid Best suffered his second concussion of the season in the loss to San Francisco on Oct. 16. A move to add more veteran depth to the backfield fell through when a trade for the Eagles' Ronnie Brown was voided after Jerome Harrison was discovered to have a brain tumor. Harrison was placed on the reserve/non-football illness list on Oct. 21. Morris, 31, is in his third season in Scott Linehan's offense and his 10th year in the league. He's adept in the passing game, an asset with Detroit passing more than running. An evaluator, speaking on condition of anoymity, said Morris is a "one-cut" runner who also possesses good hands and toughness. The Lions' best-laid plans at running back involved having Best and rookie Mikel Leshoure as a 1-2 punch, but Leshoure was lost for the season in training camp. The Lions are hopeful Best will return in 2011, but as is the case with concussions, a timetable is unclear.
