NFL free agency isn't always the best place for teams to address glaring roster weaknesses. Spending huge amounts of money (especially guaranteed money) on free agents has the potential to backfire.
But the New England Patriots need to make a splash in free agency in March. They have an abundance of roster needs on both sides of the ball, and they are projected to have the most money to spend of any team -- around $120 million in salary cap space, per OverTheCap.
The most important need for the Patriots to fill in the coming months is arguably wide receiver.
