Personally, I don't even see this as an issue of whether Lucia made Guentzel a scapegoat. A head coach has a right to "adjust" his staff has he sees fit. In fact, I'll even guess that if Lucia made a change he probably had a good reason to do so.
That said, the public explanation of what went down likely differs from the real story. And in the case of a firing described as a resignation that can also be understandable.
However, since the majority of a team's fans are going to drink the Kool-Aid on those explanations, if a sports writer wants to stir the pot all he has to do is bring out the real story, add a dash of red pepper to spice it up, and there you go. Now Reusse has joined those few MN fans who don't care so much for Lucia with fans of other schools who are mandated to hate everything about their rival (or suffer death) and pitted them against the Kool-Aid drinkers.
We should ALL thank Reusse for the off-season fun (easy for me to say).
