Winning with him doesn't happen obviously. He's been there 6 years, they had one winning year with Butler, and that was on the level of current Portland/Dallas, so not really great either. All the other times they are a lottery team. So not exactly easy winning with him, as history shows.
You overrate him, not anywhere near? What is he Embiid? Jokic? Davis? He's not even a all-star so get real.
It's not stockpiling draft picks, its about landing a (potential) marquee star or two and build from there. And I don't think Towns is that. Maybe 4 years ago he was but not today anymore. He is what he is, a talented offensive center but never a leader and his teams always underperform (except when they had Butler one season). Guys like Bosh and Love were scrutinized for this but somehow he's excused? He's at best a 3rd wheel on a championship team, and maybe 2nd option on a contender/pretender that has a genuine superstar leading the way. He will never be that in Minnesota, and they better get value while they can, and from the same perspective, he better gets to a team that gives him a chance of competing soon.
