I don't see why it has to be some grand narrative judgment about BU to go through this incredibly new and chaotic environment and assess it as a learning experience.
Dainja, Storr, and Dante Maddox are three different types of situations and in all three we said "eh, the price isn't right, we think we can do better". IF those were bad decisions (we don't know that yet), that doesn't mean Underwood is an idiot and we need to get rid of him, any more than our forays in trap-happy defense his first two years here meant he was an idiot we needed to get rid of.
BU learns. That's his greatest strength as a coach. And what I find interesting and enjoyable about following the team on this board is learning along with him. But that necessitates looking at things as they are, not making every question a referendum on who has "faith" and who has "doubt".
(And I can't help myself with this, but don't pretend I haven't seen what some of you "faithful" have said about BU in game threads and coaching carousel threads)
