No they aren't. Their best chance for franchise success is to convince Boogie to stay another 6 years. They couldn't even get draft picks willing to go to SAC to work out last draft -- tanking is the wrong strategy right now. They need to make their organization less of an embarrassment.
There is zero chance that Sacramento ever wins anything with him on the team and middling draft picks. They have virtually no other assets, no free agent prospects, and they won't even get a single high lottery talent. Gay is literally their only other above-average player on the roster and hates it there. Then they have to bet on Cousins resigning for the super max salary, so he'll be expensive as possible. Or he'll leave, since losing sucks after a long while.
On the other hand, they could have 3x top-5 talents in the next 2 years all locked into rookie contracts, and go into an offseason with 2-3x max player money. Not only do our assets give them high lottery picks in strong year(s), but as someone else pointed out tanking could turn their own pick from a 2nd rounder into a high lottery pick.
As far as the future of the franchise, this is a no brainer. Sell and tank. But, certain people want to keep their jobs and sell tickets. It's short term greed and/or stupidity, plain and simple.
I agree the "obvious" decision for the health of the franchise in Sacto would be to tank, but keep in mind, we're also incredibly biased on this side of that argument.
As for people keeping their jobs being the reason against tanking, I believe it's less that and more that their bosses are actually delusional human beings. Vlade has 0 experience when it comes to team building and worrying about things like lockerroom chemistry, personnel, play styles, etc. And EVVVVERYTHING I've ever seen/heard/read about Vivek has left me with the impression that the guy is a lunatic. Whether it was the Grantland video with him in the war room a few years ago or the interview he gave USA Today over this summer, he's got shades of our dear President-elect in him. Whatever he says is factual regardless of whether it actually happened or not. It has to be an embarrassment working under such leadership for anyone in that organization that actually knows the sport/administrative side well.
I sincerely believe that Vivek is less trying to max out Cousins to make him as expensive as possible or because he thinks Boogie is his only asset of value, than I do honestly and truly think that psychopath thinks he's only a piece away from contending for a title.
