Not sure what interview you heard, but here's a Stackhouse quote from an interview on Zach Lowe's podcast.
“People say I may not like pace,” Stackhouse told Lowe. “I want to get out and run every opportunity we can. But if we don’t have something initially, let’s bring it back out, get into my Carolina secondary offense...I like the three. I like to have weakside action, making sure that guys aren’t stagnant and just standing, making sure that we’re keeping guys occupied...We want guys driving the ball to finish, but if the helps comes, I want that corner filled, and I want that slot filled, so I can sit there blind,” and here Stackhouse closed his eyes; he wants his players to know the right play so intuitively they don’t need to see it to recognize it. If you watched Stackhouse the player, you may see his coaching philosophy as somewhat surprising. He sees it, too.
“I probably wouldn’t like my game as a coach. Midrange twos...I tell guys, ‘All right, If it’s the shot clock and a guy runs you off and you gotta take a one-dribble pull-up, OK, do it. But otherwise, let’s try to get into the paint, pull another trigger, or find something else on the weakside, or just sidestep him and take the three...Guys who have efficient midrange games are always outliers.’”
^ sounds pretty anti midrange to me.
