When it was set into motion is less relevant as to why it was set in motion.
Even if Wilson isn’t your guy, its only a $35 million hit to keep him on the roster as a backup or whatever. Its an $85 million hit to cut him. That’s $50 million the Broncos would have available for other players - with Wilson still on the roster - that is now gone.
That’s a king’s ransom of a sacrifice just to get a guy out of your clubhouse, which is why there’s gotta be a back story with there being enormous friction between Wilson and somebody or multiple somebodies.
"The biggest takeaway from Wednesday’s stunning news that the Broncos have benched quarterback Russell Wilson is that the Broncos will release him before another $37 million in future salary flips from guaranteed for injury to fully guaranteed. That will need to happen between the first day of the waiver period (right after the Super Bowl) and the fifth day of the league year, which begins on March 13."
He's not well liked in the locker room....and you added that with his play as well as this...
"the Broncos approached Wilson in late October threatening to deactivate the nine-time Pro Bowler if he didn't strike the gargantuan injury guarantees built into his $245 million contract — the very same guarantees that led to his demotion for the final two games of the regular season.
The request "shocked" Wilson, per Schultz, and "the two sides got into a major dispute on how to proceed."
"When the threat was made by the Broncos, the team, Wilson's camp, the NFLPA, and another unknown party were involved in negotiations that ended with no change in Wilson’s contract," Schultz added."
and you have your answer.
