What you need more than anything is an owner who is actually willing to eat a couple of shit years to get a process like this started. The Browns have failed over and over again in their rebuilds because they keep jumping the gun and firing front offices before they have a chance to build anything. You can't build a winning culture over night, and you can't get anywhere as a sports franchise by constantly replacing your front office because, in the NFL at least, new GMs want to bring in their own guys, and they have no investment in the guys drafted by previous regimes. If you try to flip front offices every two or three years, though, you end up in a never-ending process of letting the old regime's guys walk and trying to bring in the guys you want.
Now granted, a lot of our previous regimes were obviously various levels of incompetent, but even with those I think that, given four or five years, they probably could have put together a winning team. Of course, no regime has gotten that long since the Browns returned to Cleveland, and that's part of the reason we've been stuck in purgatory for so long.
Hopefully they'll continue to show patience with this front office and give them a couple more years to continue building what they're building, because this is definitely the most confident I've been in a front office in my adult lifetime.
