But when it comes to the blame game, Munchak is backing running back Chris Johnson, who said Sunday that he's not the source of the Titans' anemic ground game. Johnson had just 10 carries for 18 yards in the loss to Houston, and the running back, who sat out the preseason before landing a $53 million contract extension, said after the game that he's confident he's doing what he's supposed to do.
Munchak said Monday that he hadn't heard those comments, but everyone shares the blame for the struggles.
"Chris has had a great career here in three short years," Munchak said. "I think it's hard when you're going through a spot for the first time in his career, he's not having the success he's had for three years. I think all athletes struggle with that concept ... To run the ball well, it takes 10 other guys."
Johnson even turned to Twitter to reassure his fans he's still playing hard, despite having just 268 rushing yards in six games.
"All the fans who r sticking with me i appreciate it I will never give up I'm still homeless n I'm playing hard everytime I step on the field," he wrote.
