Increasing the number of games to heavier division matchups is all about money.
One, there is more demand for tix vs. division opponents b/c more at stake than some team 3,000 miles away. The games are MORE important in the standings as well.
Two, it will increase and/or develop more rivalries.
Three, cut down on all over the map travel costs.
Four, who cares if you can't see the ONE game if Crosby is not in your conference/division? Got TV? The very reason is for all the ONE game Crosby's, there's the games you are more likely than not to attend: say, if your in EDM: you wanna see FL, CAR, WASH, etc? nope...
