Yards After Contact

Our goal is to only count yards after contact if the running back is in danger of being tackled. Here’s an example of a play where technically there is contact as he runs through traffic, but the RB is never actually in danger of being tackled until he goes down. This play would have zero yards after contact.

We also don’t count yards after contact if the runner’s momentum carries him forward. This most often occurs when he’s tackled by the ankles. Any running back, regardless of strength, would fall forward on this play so we do not reward yards after contact.


If the defensive player tackles the running back from the behind, causing him to move forward, this is not yards after contact.


Most yards after contact occurs on broken tackles, but can also occur if the running back clearly uses his strength to drive forward for extra yards. On this example, a weaker running back may have been stopped dead in his tracks by the head-on tackle, but Barkley drives forward for an extra yard.


Contested Targets

A contested target is any time the receiver has to compete with a defender for the ball. The defender should be actively trying to make a play on the ball or otherwise interfere with the receiver’s ability to make the catch while the ball is in the air.

This is a good example of a contested target where the DB is making a play on the ball an interfering with the WRs ability to make the catch.

Here is another example of a contested target. Even though the DB isn’t intentionally making a play on the ball, his positioning clearly prevents the WR from making the play.
