I see this written a lot but I don't really understand it... We're going to have a draft anyway, and it's not like we get extra picks for letting players go. Or like we're going to try extra hard to draft well because Hatcher and Ware are gone.
If you mean to trade the players we do have for picks, or use them to move up in the draft, I can get that.
Really, as long as you have a franchise QB and a few other players around, which we do and have for the last several years, I don't think you tear it all down. I don't think you try to "rebuild" until you're in a situation like with Jimmy and Herschel where you have such a bad team that it can't possibly win anyway and a vet player or two who will be too old to be any good by the time the rest of the team becomes competitive.
