McClay has been considered for GM roles at least 5 times to remain as the de-facto GM in Dallas.
He is getting paid for the role and he does the actual job.
But he could certainly leave for a place where he is the sole voice, Team President.
In Dallas he has a job for life. He won't be fired for a couple bad drafts and isn't held responsible for team record.
So the grass isn't always greener.
Dan Quinn may want to run a team again. He's done everything in football so who knows what he wants end of day.
But a defensive coach with a likely future hall of fame player in Parsons is a heck of a lot more fun than wrangling cats on all 3 of offense/defense/ST.
I'd have argued the Chargers with a solid young QB were appealing 2 years ago.
But now?? Not at all. They keep underachieving and firing coaches.
Plus they moved from San Diego where you can live a nice, wealthy suburban lifestyle to insane LA where rich people with drivers sit in traffic for hours.
If Dallas does lose both they'd be VERY appealing jobs for any DC and Personnel guy to take on.
The bigger worry is how many people followed both out the door.
Could cause a season of regression to re-tool scouting and/or defensive coaching side of the ball.
