Spielman knows the draft and this team. He is a wheeler dealer and who can acquire draft capital and is not afraid to take chances. The Wilfs will need him this offseason to make some moves.
I think Zimmer can rebuild a defense as well as anyone else... so, keep him one more year to do that. If his defense doesn't improve next season, fire him then. I think Spielman has a safety net in place with Capers and Kubiak allowing him to have a quick hook with Zimmer mid season 2021 if needed.
As far as Cousins,... if we cut him and he is resigned by another team and plays in 2021... does some of that new contract comes off of what the Vikings would owe him?
