Since When Did First Time HCs Have a Say in Finding a GM Become a Trend?

It has been well documented with the bears over the last 10 years. They hire a GM keep the coach. Then the GM fires the coach gets his coach and QB. Then he gets fired and it repeats. Most coaches want a GM that they are tied with so they will have more longevity and say.
I know in the Bears last coaching hire, there were certainly GM candidates tied to certain coaches. But the crazy thing is, once they hired Ryan Poles, they basically told him to choose between Matt Eberflus, Dan Quinn, and Jim Caldwell. Now, in fairness, they had asked him to name some of the coaches he felt he could work with and Eberflus and Quinn's names had both come up. And there was some particular reasons why Ryan chose Matt, which were incredibly shortsighted. But still, he had another coach in mind he wanted at the time (was at the top of his list) but the Bears hadn't interviewed the person. So, in a sense Ryan made the choice and in a sense he didn't.
