Not trying to be combative, but the past couple Patriots drafts have been as hit-and-miss as others. They had quite a few stinkers in the late 00's, and even now they have an okay track record.
Drafting is always a crapshoot. The Lions aren't great at it, but few organizations (Steelers, Ravens, Packers) do it consistently well. The Patriots just have one of the best QBs in history playing with a very disciplined and committed coach and process. But they lose Tom Brady, I think they are a .500 team.
