Dave Rogers calls Greg Biffle a coward

Dave Rogers, the crew chief for Joey Logano's NASCAR Nationwide Series team, called Greg Biffle a coward after Biffle pushed Logano into the wall during the race at Auto Club Speedway on Saturday.
Logano rallied through the field and worked his battered car to the front.
Biffle ended up getting collected in a wreck late in the race and finished 14th.
Logano and Rogers said after the race the best revenge was winning.
