The WR Corp should improve. Dobson, Thompkins, and Boyce are going into their second year. Edelman is back. Amendola; if he can stay healthy; perhaps can regain Brady's trust. At least this group doesn't have the same learning curve as last year.
Secondary Should Be Better - The addition of Revis and Browner should be a significant step up. If Revis can stay on the field all year and in the playoffs, he shouldn't have any problem filling Talib's role/importance as being a catalyst for the defense.
Getting Injured Players Back - Gronk, Mayo, Vollmer, Wilfork. Seemed like the entire roster was playing hurt at one time or another. Hopefully, this year will not be as bad.
Collins has a good chance of making leaps and bounds in his second year. I'm optimistic that BB will find unique ways to let him loose (but not holding my breath)
RB Corp still above average. If Vereen can stay healthy, it'd be nice to see him in an expanded role.
I'm much more optimistic about this year's team and position vs. last year.
If we can improve the TE postiion, SS, OL can stand strong come playoff time, and our pass rush can be improved.....the sky is the limit.
