The Browns was a different situation with an unproven QB and HC and New WRs in a new offense (Beckham and Landry)
This situation is different. There's a proven competent QB in Brady. A proven HC in Arians. All of the WRs and TEs and playmakers are not new to the team. They have been there.
Not so sure with an aging quarterback. He is going into a new system. Yes I feel a little nervous but most of attention is what we do now, in the draft and training camp.
