Rubio was a decent enough pick (of course with hindsight you'd take Curry, but most at the time probably would have taken Rubio). I think at the time everyone thought that Flynn over Curry was stupid. And it turned out to be so.
The worst part about taking Flynn was the Wolves then traded him a couple of years later. And got Nikola Mirotic and Chandler Parsons in the deal. We then immediately traded Parsons back to Houston for cash, and traded Mirotic for what eventually amounted to cash.
