The Regression of Patriots Special Teams in 2018:

[Ring 6]

And football has many variables that other sports don't (e.g. a QB is evaluated on how well his OL blocks, his receivers catch the ball, and etc...whereas baseball...it's only the hitter/pitcher and in the NBA it's PER).

Not to mention situation.
How you perform when the game is on the line which may be 5-10% of your stats is more than 50% of your value.

Maybe its kick off new rule formation. Before KO Team had a head start to run down field. Ghost could send it to a corner where Returner was boxed in for short ydg at or before 25 yd line. Looks like Returners are already at 20 yd line before any Pat is near him.

That's definitely part of the puzzle imo.
