The Dillon 10 carry or less parameter is pretty simple, it demonstrates that when Maroney doesn't have another back who carries a large share of the load his effectiveness deteriorates dramatically, to the tune of
3.06 ypc in 2006, behind the SAME offensive line, and sharing the offense with a crappy group of wideouts. So no OL excuses can apply, and no we have a "historic air attack" excuse can apply either. These stats merely prove Maroney's unsuitability to be "the" feature back.
However when you compare games in which Maroney split carries nearly 50/50 with Dillon his YPC grows to a respectable
4.22. Similarly Maroney was enjoying success earlier in 2007 when Morris was there to help shoulder the load. But by himself, Maroney has struggled, thus the
3.04 ypc over the last 5 games. Glad I could help explain the methodology to you.
Let's be honest with ourselves people, it's not a disaster if Maroney is only suited to be a good #2 RB, you just need to find another RB to take over the #1 role, and you'll likely find that Maroney should be fairly productive, and comfortable in his sidekick RB role.
