Hire him for $1 and keep him on the bench for the season.
Give him a couple of weeks to get up to speed, or even change Green Bay's offense to the 49ers offense that Colin (kinda) knows how to run.
Do every single thing to accommodate and appease and to defer to him, on and off the field.
Let him have his own TV show, like a coach's show, except he gets to scold anyone he wants for racism or whatever.
"Yes Colin, Of course Colin, Whatever you say Colin."
Just totally let him have every D$%^ thing that he wants, and make everyone totally deferential and submissive to him... and then watch it all go down the tubes.
It would ruin the Packers, of course, but it doesn't matter, because Colin and Roger and their ilk have already ruined the entire League.
Oh... the last part. Colin gets to be accountable for it all.
One would suppose that all he could do after that would be move back to SF and run for office.
