Stupid.
Yea, let's split up NY-PHI, nevermind 40 years of history, let's be the only sport where teams 75-90 miles apart are separated.

personally I don't agree with the thinking that 4 Divisions offers more "flexibility" for "team movement and future growth".
"Flexibility" all depends on the members in the League, not on the number of Divisions. And it's the two northeastern Divisions which are the most 'inflexible', and even with 4 Divisions there is little potential that the alignment groupings of those two Divisions wouldn't be effected. IN Fact, there is much speculation that those two Divisions have played a big role in likely squashing the 4-Division idea, in part for that very reason.
As for future growth... If the League can go with unbalanced Divisions now, as you and some others might like with a 4-Division setup, and having that with Expansion likely no sooner than at least 3 years after the 2012-13 Season... Then the League can equally live with unbalanced Divisions within a 6-Division setup. And it's that "unbalanced" scenario which actually offers more "flexibility" in alignment because the League can pick and choose, with possible movement of teams, which Divisions get 5 teams and which get 6 teams. The "flexibility" offered by 4-Divisions only really exists as long as the unbalance exists.
This is actually pretty good reasoning. If the major impetus for moving to 4-divisions is flexibility, would that mean that these same people would move to 6-divisions once we get 32 teams?
I think when I originally had the 4 conference idea it's purpose was to nicely reflect geography (particularly in the West). The flexibility in accommodating relocation was a bonus.
