IRVING, Texas -- The key to the Cowboys' running game might be a man with one carry for no yards this season.
There is strong statistical evidence to support that theory, although it's a small sample size.
In the two games fullback Tony Fiammetta has played, the Cowboys have 419 rushing yards, averaging 7.0 per carry. They rushed for a total of only 299 yards in the other four games, averaging 3.0 yards per carry.
"I think he’s the best blocking fullback we’ve had since Daryl Johnston," Jerry Jones said on KRLD-FM. "That goes a long way.
"The fullback effectively splits a defense. It lets you block up in there, man up with an extra player that you don’t have when you’re not playing with a true prototype fullback."
Fiammetta, who the Cowboys claimed off of waivers from the Panthers, won't take that much credit.
"It’s definitely not one man," Fiammetta said. "I think everybody has been working toward this end and toward getting the running game going. I wasn’t here for training camp, but I’m sure they were working hard then and it’s just starting to click."
It's clicked when the Cowboys have a fullback and sputtered when they haven't.
