For hardcore football guys to a point, yes. Guys on defense are getting tired of the offense switching Harrison, Moss, Holt etc putting them up against other cb's to have them beat.
Defensive assignments was one of the best things. By having a Bailey on Moss the whole game you didn't have to worry about where Moss was lining up then had to focus extra attention on him so your crappy cb wouldn't get beat down the field.
It is serious when a part of the game gets exploited and the defense can do nothing but "guess" where the top receivers are going to line up.
