NFL league year began March 12 with the tampering window opening spending on March 10. Here's who has the most salary cap space and least.

These five NFL teams were all active in free agency this month, and they all look better as a result. The Patriots added real talent to the defensive side of the ball with big additions like defensive tackle Milton Williams, outside linebacker Harold Landry, inside linebacker Robert Spillane and cornerback Carlton Davis.

Outside linebackers Dre Greenlaw and Leonard Floyd, safety Talanoa Hufanga, cornerback Charvarius Ward, wide receiver Deebo Samuel, tackle Jaylon Moore, guard Aaron Banks and quarterback Joshua Dobbs are all out the door, and most of those guys will be hard to replace outright.
