Let's go ahead and explode the MYTH that a great passing game necessarily means a poor running game right now.

In 2004 Peyton Manning threw for a record 49 touchdowns.
How did his teammate Edgerrin James fare?
1,548 yards 4.6 YPC and 9 TDs
A few issues this this. First and Foremost, James was not in his 2nd year and coming off shoulder surgery. James was a 6th year player. Also, James was more of an all-purpose back than Maroney. And James didn't have to share carries with Morris. Nor did James miss any time. So you are comparing apples to oranges.
OH, btw, the Colts had 954 plays from scrimmage that year. The Pats have 732 plays from scrimmage so far this year. They are on pace to hit 1064 plays from scimmage. Manning had 497 passing attempts. Brady already has 400 through 11 games. Brady's on pace for 581. And 57 TDs.
In 1999 Kurt Warner led the "Greatest Show on Turf" with 41 TD passes.
How did his teammate Marshall Faulk do?
1,381 yards rushing 5.5 ypc and 7 TDs.
Marshall Faulk was in his 6th year as a player. He also had a great offensive line that year lead by Orlando Pace. Warner had all of 499 pass attemtps that year. The Rams had 431 rushing attempts. Again, look at the difference in the number of pass attempts between the Rams and the Pats.
Because Faulk, like James, was more established, he wasn't sharing reps. Faulk also wasn't coming off shoulder surgery nor did he get injured that year. Again.. you're comparing apples to oranges.
In 1984 Dan Marino set the passing yardage record with 5,048 passing yards.
How did his teammates do?
1,918 yards total rushing and 18 rushing TDs
Marino had 572 attempts.. so that seems about right. The Dolphins also had 484 rushing attempts that year. Total of 1056. Pretty close to what the Pats will put up.. Now, the difference? Marino threw 48 TDs. Brady is on pace to throw 57.
Did you stop and look at the RBs that year? How many did they use? 3 different RBs had over 100 carries. Woody Bennett (7th year) had a career year with 144 rushes. Tony Nathan (6th year) had 118 rushes. Rookie Joe Carter had 100 rushes. Their short yardage back had 68 carries and 9 TDs. It was his 9th year in the league and only one with Miami.
Joe Carter was out of the league 2 years later.
Look at the Pats RUNNING game in its entirety. The Pace they are on, they will have 17-18 TDs. They'll put up 1986 rushing yards. Hmm.. those numbers seem pretty damn close to the numbers that Miami put up.. Hmm.. Imagine that.
The only thing a great passing offense might take away from is the number of rushing TDs. Historically it has done nothing to limit the production of the team's running game in terms of total yardage and even average per carry.
