Except for the ones that build and add good players around him. prove it you ask? Ok sure , remember what happen when Brady went down? patriots still won what 11 games? I get your point tho.
And we were winning games with Matt Flynn despite having an injury decimated Defense. The thing about this team, there are about 4 high upside players from the last 4 drafts that are still on the roster and the team hasnt given up on them. What if Nick Perry stays healthy all season and continues showing the pass rush he showed in limited action last year? What if Derek Sherrod makes a full return and Bryan Bulaga is able to stay healthy? This team would get a heck of a lot stronger on both the Offensive line and the front 7 without adding any new players.
