The New England Patriots can replenish the offensive line via the NFL Draft starting with Sebastian Vollmer in calendar year 2013 and Dan Connolly in calendar year 2015. The New England Patriots currently have seven offensive lineman under contract for the 2013 NFL Season that are currently on the 53 man roster: Solder, Cannon, Zusevics, Mankins, Connolly, Wendell, McDonald. Donald Thomas may, once again, be inexpensive to re-sign on a one year deal.
The combination of running backs Shane Vereen and Jeff Demps should replace the skill set of running back Danny Woodhead in calendar year 2013.
Tight end Jake Ballard should replace tight ends Visanthe Shiancoe and Michael Hooman (or whatever his last name is) in calendar year 2013. There will be no need to keep five tight ends on the roster for the 2013 NFL Season with Gronkowski, Hernandez, Fells currently under contract for the following season.
Shane Vereen, Jeff Demps, Jake Ballard will not be vested veterans in calendar year 2013 since none of the aforementioned three will have accrued four NFL seasons.
