Mike is right. The Wolves never tanked like the Sixers. Moving on from Love, who wanted out, is not tanking. Signing Pekovic, Dieng, and Rubio is not tanking. Hiring Thibs is not tanking. Just because they are a young team with several guys with very high upside does not mean they have been trying to lose games.
Wolves moves of note since July 1, 2014 (not including the draft)
Trade - Love, Mbah a Moute, Shved for Wiggins, Bennett, Young
Re-Sign - Rubio
Trade - Brewer, Turiaf for Daniels, '15 2nd, '16 2nd, cash
Trade - highly protected '17 1st (likely will be a 2nd) for Payne
Trade - Williams, Daniels, cash for Neal, 2nd
Trade - Young for Garnett
Trade - Osman, Christmas, 2nd for Jones
Re-Sign - Garnett
Sign - Bjelica (who was a draft pick of theirs from 2010)
Sign - Miller and Prince as free agents
Waived - Miller
Waived - Martin
Fired - Mitchell
Hired - Thibs
Sign - Rush, Aldrich, Hill in free agency
Re-Sign - Dieng
That doesn't exactly strike me as a team that is trying to win. Strikes me as a team that pretty consistently traded veteran talent for future assets and signed a couple of veterans that wouldn't move the needle in the win department at all while re-signing a couple of their young guys (Rubio and Dieng).
Did Minnesota go around announcing to the world that they were tanking, of course not, but they were clearly tanking. Their moves in the last 2+ years all lead to that conclusion. Now obviously they hired Thibs because they thought he was the guy that could get all of that young talent they had acquired to start living up to the potential. Thus far that hasn't happened, but I would expect the Wolves to start making win now type moves because they have Towns and Wiggins to build around with Lavine and Dieng showing nice promise as 3rd and 4th options. You tank to acquire what you believe is a championship core. You stop tanking once you acquire those players. The Wolves and Sixers both are entering that building towards a winner phase because they both acquired what they believe to be a possible championship core.
