I agree with your entire post. Yes, I think the nepotism will be strong in those hires.
And the vikings need to do a semi start over. They have a lot of talent in their prime, so you still want to contend, but you need to get rid of guys when its time. Cook and Smith need to get traded. Cook is hurt all of the time, and you just cant afford to give good money to a RB. Smith doesnt appear to be the elite player he once was, so if they could get something decent for him, Id do it.
I'd also try trading Thielen. Hes getting up there in age, and I'd gladly take a second or third.
They also need to cut Griff (who ran out of gas in second half of season), Reiff (who makes really good money for an average at best tackle) Linval (vikings do not stuff the run anymore, i think linval is done) Rhodes (no explanation needed).
Therefore you could use some of the money to resign Anthony Harris, Mac Alexander, and maybe another OLineman. Additionally, if you could get draft capital with some trades, fill some more holes that way. Maybe even draft a QB.
But Cousins needs to go after this season
