Momentum on a free kick

[maven]

My observations:

1. The R is out of position, having to run back to the GL to rule on TB. He should start straddling the GL.

2. I can't see where the receiver gained possession.

3. He gives an NFL TB signal (NFHS and NCAA use a "fair catch" signal for TB).

4. No clue why we're starting at the 2 YL if the ruling was a TB, but the R seems to be lined up directly behind the QB.
