They wanted a young center coming back and Detroit doesn’t have any centers who are both expendable AND better than Marco Rossi. Ohgren is a Carter Mazur level prospect and Buium is comparable to ASP.
So basically Minny gave up a package equivalent to a better Danielson/Kasper, ASP, Mazur, and a 1st. I’d have been happy to trade something like that for Hughes, but we just didn’t have the premium piece they needed at center.
