The biggest film study improvement started like 20 years ago, didn't it - with the printouts available to players right on the sideline, moments after a drive has ended. That's useful, for sure.
But I went with analytics (surprise!). No, football hasn't bought in, which means there's still massive inefficiencies that will be exploited by whoever has the balls (and brains) to be the first. Going for two, going for it on 4th down anytime you're past your own 40, I believe it is, onside kicking more often, etc.
But football coaches are sheep. Hell, the NFL encourages the herd mentality by fining a player for wearing his socks wrong or a different colored shoe. The big point here is that if a coach fails by doing things the same way as everyone else, he'll just lose his job. If he loses by doing things differently, he'll lose his job and be made fun of.
A franchise like the Browns need to crank up the analytics and PUT THEM INTO PRACTICE. The Browns suck, they've sucked for 30 years, and they're likely to continue sucking. Why not try something different? Anything different! Except that everyone is so damned risk-adverse, that they avoid risk even when something is statistically shown to be beneficial.
