Most of the New England Patriots' needs are on the offensive side of the ball heading into the NFL offseason. That is common knowledge.
The Patriots need wide receivers, they need offensive line help and they could also probably use another running back.
But one would be remiss to dismiss the issues New England has also had defensively this year, which is why the Pats should also be pursuing some help in that area, as well.
One of the most important aspects of a good defense is having lockdown cornerbacks, and the Patriots already appear to possess an up and coming one in Christian Gonzalez.
