You make absolutely no sense. You talk about being a disaster for the playoffs. Yet, you acknowledge that Edelman is a high quality #2.
If Edelman is a high quality #2/#3, and Amendola is this year's Welker (as he should be for the playoffs), then not only is the offense not a disaster, it will be one of the best offenses in the NFL. Our running game was #7 and is at least as good this year. Vereen should be a fine 3rd down back by the time of playoffs.
The only real question mark (other than health at the time of the playoffs) is whether one of the rookies can step up to be an OK #2/#3 receiver, or can at least do this by committee.
Of course, if they are ALL looking bad, we could re-sign Jenkins or Hawkins.
This is hardly a catastrophic offense.
