As Foster continues to look smooth, Jay Ajayi rehabs a knee issue on the sideline. Asked about the Dolphins' 2015 committee approach at running back, OC Clyde Christensen said it's something the team hopes to avoid. "We really need someone to emerge as the guy," Christensen said. "We don't want to substitute. ... We really need one guy to be a three-down back, stay in there for that drive." Every indication has been Miami wants Foster to be that bell-cow.
