They already have those analytics. And they don't care about them.
"Moneyball" in MLB, which I could debate didn't actually work, isn't just based on analytics. It was based on analytics, combined with the notion that a franchise couldn't or wouldn't spend top dollar on pretty much anybody, because they simply couldn't afford to.
Which NFL team fits that mold currently?
The forward thinking coach and GM will find themselves blogging if they make a mistake. Nobody blames those guys for the deals they gave Goff or Wentz. That's why they still have jobs, despite the deals and subsequent trades. Its a fireable offense to not re-sign Lamar Jackson, have him to go another team, win a bunch of games, and his replacement, whoever that is, win less.
The only team(s) that could even consider doing that, is a team who's GM is also its Owner. And even then... Ownership is risking lower revenue from lower profile players, which is why they don't bother.
In the end, I come back to the same question I always ask... With a salary cap north of $200M (except for this year, of course), why is $160M not enough to fill out the rest of your roster? The teams that can't compete with a $40M QB can't compete because they're not good at talent evaluation, and giving them more money isn't going to fix that. They'll just spend the money on free agents who won't live up to the contract.
Or basically, you'll end up like the current Dallas Cowboys.
