Ignorance, huh?
Who got added in the east? Nagbe in Columbus, Gressel in DCU. Know where those players came from? THE EAST. (Columbus lost Accam,whom I would take over Nagbe btw)
Other than that, you want to make the case that some CB on loan from Palmeiras has changed everything for Orlando, or this Dutch LB from Vitesse has made NE scary, or Tabla's return means Montreal is awesome (even though it seems they are losing Piatti), be my guest, sensei.
Atlanta blowing it up is the only meaningful change in the east.
