The Patriots have given Jerod Mayo a 5 year contract extension. Now if Brandon Spikes can get back onto the field and stay healthy, the Patriots will hopefully be able to build up a better defense around these two guys in the future. When Mayo is on the field he is simply a tackle machine. Couple that with the intensity that Spikes brings and you got a line backing core that any team would be proud to have on the field. Any RB who goes up the middle and makes it through Wilfork is not going to want to see these two guys.
