It probably is wise for an organization that continually makes bad decisions DESPITE their very own data telling them to act differently, to actually follow the data.
Remember that their coach actually wanted Carr but the owner met some homeless guy that convinced him to draft Manziel? (Also, can someone find that homeless guy and give him a sales job targeted at working with C-level execs?)
The issue is that Moneyball approaches don't generally win you the whole thing, but they will make team more effective with less money/ resources over the long term. So, it makes a small market team more effective vs the bigger pockets of another team - but again, we are relying on less failure over time, not more success.
But the Browns are on record as having come to the right conclusion repeatedly, and then for some unknown reason, ignoring it and going a different way. They don't listen to their scouts, they make bad personnel decisions, and the guys they do hire they provide little support to or force them to move in directions that assure failure.
So if this guy can just remove half of the utterly stupid counterproductive moves by the Browns, maybe they won't be such a nightmare. I actually feel bad for their fans.
But given data, analytics and decision-support tools are just that: tools. You still are stuck with tools only being as good as the person using them. At some point, they are going to need to get good football people in there and I cannot fathom good football people will want to even get on the plane to meet these guys.
Because they don't even listen to the good football people they have now.
