Denver. It's the only offense in the league that I could see finishing the season with a 4000 yard passer and a 2000 yard rusher. Their O-line has been absolutely MONSTROUS in the preseason, especially in run blocking.

It isn't even the only team in the West that "could" do that.
Not even the most likely to do so.
I will not argue that Kansas City is fully capable, and perhaps even LIKELY, to finish the season with a 4000 yard passer (assuming Green stays healthy). However, Kansas City's RBs over the last 3 seasons have COMBINED for 2069 yards, 1677 yards, and 1833 yards. Only once have they broken 2000 as a unit. I doubt the TEAM breaks 2000 yards this season, let alone a single rusher. It would take a MAJOR offensive shift to accomplish the feat.San Diego's QBs combined for 3468, 3205, and 3348 yards over the last 3 seasons. Their RBs have combined for 1910, 1728, and 1831 yards over the last 3 seasons. While I don't dispute that Tomlinson is the kind of horse necessary for a 2000 yard season, it would take a major offensive shift for San Diego to finish the season with EITHER a 4000 yard passer OR a 2000 yard rusher.
Oakland... well, Oakland is Oakland. Oakland was dead last in the league in rushing last season, and have made no real improvements to the offensive line. I give Jordan pretty much no shot at rushing for 2000.
And now we get to Denver. They had a 4000 yard passer just last season. Denver has already produced a 2000 yard rusher once, and starting RBs in Denver average over 100 yards per start. Anderson got 1500 yards in 12 starts in 2000, which pro-rates to a 2000 yard season. Their RB rushing totals over the last 3 seasons are 2060, 2238, and 2052. All it would take is a slight increase in total offense from last season and Anderson and Plummer to stay healthy all season, and I could easily see them finish with a 4000 passer and 2000 rusher. I'm not saying it's LIKELY, I'm just saying that they're the only team in the entire NFL that I could realistically see accomplishing the feat.

KC, St Louis, and Indy could do that imo
KC I've already addressed. Indy's RBs combined for 1821, 1631, and 1368 yards over the last 3 seasons. I don't see them realistically producing a 2000 yard rusher. St. Louis's RBs combined for 1516, 1370, and 1236. Mike Martz is famous for abandoning the run. The Rams haven't had even a *1000 yard* rusher since 2001, forget about 2000. In fact, I see them as one of the least likely teams in the entire NFL to spawn a 2000 yard rusher.Realistically, the only teams I could see producing a 2000 yard rusher are Baltimore, Pittsburgh, Denver, New York Jets, and possibly, POSSIBLY, San Diego. And of those teams, Denver's the only one that could realistically finish with a 4000 yard passer... since they did it just last season.
