Well, they have done it he right way. Most of their team has been acquired through the draft. This leaves you with young talent that can eventually work their way into the starting roles to replace the aging talent as they get to the end of their early contracts and start to command more money. This leaves cap space to gfo out and grab a few free agents to fill in holes or simply add more ammo to an already deep team.The Patriots built their team through both the draft and free agency. 'Nuff said.
Pittsburgh is another team who drafts really well. In fact, I have always felt they were the best at it. I don't know how I forgot them at the beginning of this thread. It seems like they let a big name free agent go every year and some no-name rookie or second year player steps right in and they don't miss a beat. When that player comes of age and commands a huge salary, they find another young, cheap player to fill the hole created by his release, etc.
The Rooney's have perfected it, really, They rarely miss on the first day's picks and you almost never hear of any players with character issues. They should be emulated more...
