If I'm Dennis, the answer is, I do very little. And why should I? What's my motivation?
The win total for the team has increased every season. Ticket prices were recently increased, IIRC. And I'm sure Mitchell has resulted in merchandise sales going through the roof.
So why should Dennis do anything even remotely risky? There is very little upside if he makes major moves in the hopes Utah wins 55-60 games and contends for a title. Utah is a franchise where being "good enough" has been "good enough" for 35 years. Dennis has done a terrific job of maximizing profits by keeping payroll dollars low. Operating in the black was always important to the Millers and for a BoD, it would be no different.
The downside risk is much higher for Dennis if he makes a major move that doesn't work, including job loss if he really screws it up. So if I'm Dennis, I just keep playing it safe as much as possible. The usual dog and pony show run by Perrin of bringing in 70 or so prospects. A "safe" draft pick. Pretending to kick the tires by calling the handful of agents (along with my assistant) representing the second and third-tier FA's (just so I can "show work" to Pres. Starks and the board). Pick up Derrick's option. Make Rubio an offer, but don't really care if he turns it down since the wind seems to be blowing in the direction of the fans wanting a different PG. If he leaves? Simple. I go out and sign the best FA out there who will take $5-$6M. And then I promote Naz, Cavanaugh or one of the other Stars' players to take the last roster spot.
And to the fans...I again sell the concept of connectivity and internal development. And recycle the tried and trite phrase of looking at every means possible to improve the team, but free agents were overvalued relative to their contribution and we really like the guys we have.
My name is Dennis Lindsey and I have this GM job for as long as I can keep the Jazz in the playoffs.
