The Facts: The Panthers may have given up on all-time leading rusher DeAngelo Williams, but they haven't given up on the two-back system. HC Ron Rivera said on Wednesday at the NFL owners meeting the Panthers ideally would like to get about 15 carries from Jonathan Stewart and then 8-10 from another back. "The thing you've got to be careful about in this league is you can't rely on one player at one position,' Rivera said. "Running back has definitely been proven that you've got to have a good two-back tandem." The Panthers have Fozzy Whittaker and fullback/running back Mike Tolbert to spell Stewart. But neither can replace him without a dropoff

Diehards Line:in talent like Williams could. So look for that other back to be found in the NFL draft. The Panthers hosted Georgia's Todd Gurley, expected to be the first or second back selected, last week. According to ESPN.com's David Newton, they also have shown interest in Indiana's Tevin Coleman, Southern California's Javorius Allen and a few other backs who would be second- to mid-round picks. "We're looking for that complement to Jonathan," Rivera added. Stewart proved to be one of the most productive backs in the league last year when healthy. He led the NFL in rushing with 437 yards from Weeks 12-15 while Williams was out with a broken hand. The Panthers just want to make sure they remain productive when Stewart can't play or needs a rest.
