I gave Minnesota a pass at the start of last season when they had no DPs because their entry was expedited -- rushed even -- and I thought their explanation that they wanted to take their time was credible. Now it's obvious they just don't want to spend money, in a league where that is increasingly becoming a recipe for guaranteed mediocrity at best.
This really undermines MLS's credibility in choosing expansion partners, though it also highlights the trade-offs. There were alternatives in Minnesota. MLS chose an existing lower division team with history and passionate fanbase and committed to building a SSS over creating a new team with an owner who wanted to share a football stadium but also would, I'm quite certain, have spent considerably more on talent. It's arguably defensible to choose the former, but only if the vetting process demonstrates that the owners they picked have the resources and commitment to make at least a minimal spend on players, which it seems Minnesota clearly lacks.
