Tolbert hopes he's 'the missing piece' for Panthers

FB Mike Tolbert proved his versatility in four seasons with the Chargers. He scored TDs (21 the past two seasons). He caught passes (54 in 2011) and twice lead ST units in tackles. What's his role with the Panthers? “I'd like to think that I'm the missing piece,” Tolbert told panthers.com. The Panthers opened OTAs Tuesday.
