I will also say this:
There is no guarantee this will work. Andrew Berry might be a fraud, just another in a long list of highly touted but ultimately unsuccessful NFL FO guys that come to Cleveland and fail.
To place the blame at the feet of analytics is foolish, though. There are plenty of examples of athletic and statistical thresholds that can help in player evaluation. It's not everything, though, and you still need someone who can correctly evaluate tape, identify talent. It's not like they can just run a computer simulation and just draft the guy with the best numbers.
Guys like Elliot Wold, Alonzo Highsmith and even John Dorsey have shown they can identify talent. To that end, so has Andrew Berry. They need more people in the organization that can identify these players and, ideally, do it at a better level than most NFL teams. Which is why I support the analytical approach to these things, because more information and quantifying any sort of success is important to take that next step.
I was a big fan of the Sashi approach. I think Berry will be, roughly, the same sort of philosophy to team building and approach to FA. Hopefully Berry has a better success record than Sashi had during the draft.
