Will The Lions Have To Replace Jahvid Best?

Report: Some in Lions organization fear that Jahvid Best’s career is over | ProFootballTalk. A history of concussions have left the career of Detroit Lions RB Jahvid Best in doubt.

When Best was initially lost for the season, I thought the Lions would miss him. But they're so dependent on their passing game, and they got a boost by re-signing RB Kevin Smith, that their offense didn't miss a beat. Maybe Smith will return in 2012, and their 2nd round pick from 2011, RB Mikel Leshoure, should return from a torn Achilles.

The Lions have big salary cap problems and some key players to re-sign, such as DE Cliff Avril, and they may unable to do much to replace Best. Should it be a priority for the Lions to sign or draft a running back?
