If you had your All Pro back and were happy with the young players who rose to the occasion last year, not to mention your first round pick, knowing you had to replace that all pro in the near future, why would you hang on to a 33 year old who'd played 5 games and was coming off an injury?
Talk about seeing the writing on the wall.
The Patriots will likely not luck into a pick high enough to replace Wilfork, they'll need to find at least one diamond in the rough. Maybe the trio from last year, or one of the fistful they are cycling through every week.
Surely, a castoff that turns into a diamond isn't going to develop like that sitting while tommy Kelly plays. He can see that and told his agent to find a team that needs a seasoned veteran, and he did.
Even if Easly is an All pro, we're still short a quality starter unless at least one or two players develop and that's even if we keep using firsts, because a bottom round pick is not a sure thing (fingers crossed).
