This isnt what most teams do?
some of the tracking data and stuff like that they use so that they dont need to rely so much on the measured data hasnt been available (or existed) until fairly recently - and in the past interviews and stuff like that with prospects at the combine and senior bowl were much less regulated than they are now so it required all hands on deck to make sure you got valuable time with prospects you wanted to talk to (like there are stories about trading prospects with other teams by taking them down the back corridor of the interview rooms so that no other teams could snipe them away - or even worse, steal their interview time with another team)
now they're able to record the interviews (if they're not done virtually anyway)
but for sure - there's a lot of stuff there that should have been obvious but football has been a sport of dinosaurs until fairly recently who had very little interest in renovating front office and back room processes despite massive advantages existing there to exploit
i imagine there are some other teams that do similar stuff (or maybe even more advanced stuff too or go about it differently but similarly interesting) - but some organisations are also more secretive about everything they do (and snead doesnt have that luxury in the same way that other GMs do because he's literally married to an NFL reporter lol)
