I think that what theyre saying at the press conferences isnt necessarily how they really look at it. And to answer your question, yes I think that they know it will take at least two years to be competitive the way they want to be.
This year, go with what Mcdermott knows and shore up the D. Draft your QB in 2018 and use that year to get the offense together. If the stars align, Brady retires, and you make the right moves along the way, we should have a team in 2019.
