While the Patriots were able to do well mainly playing with backups such as Matt Cassel, Ben Jarvus Green Ellis (A.K.A, Law firm), and a whole slew of guys on the defensive side the ball last year, here is who I think they should target to put depth into there roster.
I think in free agency, the Patriots should make upgrading right tackle their number one priority. With Tom Brady coming back from his torn ACL, the Patriots can not afford to lose him for good this time.
That is why I think they should target Carolina's Jordan Gross.
Gross is coming of a real productive season making it to the Pro Bowl and helping the Panther running game to become one of the best in the league. But if the price tag is too high on Gross, I think Jon Runyan or possibly Mark Tauscher would fit nicely.
On the defensive side of the ball, I think the Patriots should upgrade through the draft because it seems like defensive backs always sign for alot higher than the Patriots can afford. I think it would make sense if the Patriots drafted Vontae Davis out of Illinois.
