Jamal and Rose are two of the most delusional players in the league, and Wiggins is totally apathetic. I don't think anyone can "instill the fear of God" in those guys.
Their roster isn't built to have spacing. They've surrounded an offensive-minded big man with mostly chuckers, slashers and guys who can't shoot. Towns himself is actually the best three-point shooter on their whole team. They're still top 10 in points per game and offensive rating because of raw talent, limiting turnovers, getting to the free throw line and getting second-chance points off of rebounds. But they're always going to look ugly while doing it, and it's always going to get exposed against real defenses in the playoffs.
