18 Game Schedule?

There has been some talk this NFL offseason about going from a 16 game season to an 18 gamer. At the same time they'd drop the number of preseason games from four to two so the overall number of total games would remain at 20. Word is that the commissioner backs the idea and that usually means that it's only a matter of time before this will come to pass.
The sticking point is the players. Two extra meaningful games means more chance for injury. It also means that their per game pay will be reduced. The pay thing is probably the bigger thing but everyone hopes that more season games means bigger TV contracts and bigger paychecks for players. This doesn't seem insurmountable.
At first I loved this idea. Four preseason games produce about six quarters of real(ish) football. Going to two games would still bring about the same amount of watchable action. And two more football Sundays? Yes, please. But I've got some objections . . .

• The NFL has worked hard to not have games on Labor Day weekend. In theory this could shift the first preseason game two weeks later and end the season in mid-January. That would put the Super Bowl into the middle of February. Of course they could do the sensible thing and just move the opener up.
  
• We currently have a very balanced schedule with only two different games for each team within a division. Adding two more games would screw that up. This isn't that big of a deal but it's nice to be able to compare apples to apples so completely right now.
• And the biggest one, this will mean less drama. The NFL currently has a problem with meaningless games in the last week of a 16 game season. With two more weeks you'll find more teams eliminated with more weeks left to play. And of course the winning teams will have even longer to rest their starters. The Colts will have three empty games at the end rather than just two.
  

Hopefully I'm wrong about this because I really do think it's on the way.
