Analytics are most useful IMO in baseball where the individual nature of the game at bat and in the field leads to stats that are almost entirely attributable to singular effort.
In the NFL they are still useful, but get convoluted when you consider the scheme and how blocking from the next man over can affect the performance of a given player X or Y.
For quarterbacks there are so many factors. Does the line hold blocks for an acceptable time? Do the team's receivers have the ability to separate down the field? Do tight ends block or are they simply receivers that fail on one on one blocking assignments, causing blind side hits on the QB, etc.
There are ways to break these types of plays down too, but at a certain point the results are a bit convoluted.
What I do believe in strongly is the POSITIONAL value of certain players in the league and how important X or Y position is to winning in the league.
Those teams like Washington that spend all of their draft capital on a certain player position group, the defensive line, and spend few resources on another, the offensive line, are not going to be successful.
Left tackle and center are from what I am gleaning important positions in analytics for the QB and when you don't have solid players there that can win their matchups, you don't have an offense that scores and is productive.
Ditto on defense where a high rating is placed on cornerback. Cornerback is a position where Washington's performance in 2023 is by my guess among the worst in the NFL overall.
The CB win rate on a per pass/target basis has to be very low for Forbes, Fuller and Co.
