This can be sold as a positive.
I think Pollard has his mind made up either way. I've thought that for several weeks — since whenever a realistic shot at a tournament bid was toast (and especially with so many "almosts" piling up, again, around that time).
If JP decided he's keeping GM no matter what, he's going to have his fingers crossed that something unbelievable happens the rest of the way (I'm thinking a serious run in the B12 tournament at minimum), otherwise his decision will alienate at least a portion of the fan base — he'll have to sell some kind of hope, and as sweet as this win was, that's not enough.
If he has already decided to handle the financial realities and cut the strings, I guess it might anger some GM diehards if an improbable run transpired ... but there are coaches who've been canned even after having a good season with a tournament bid, because it was based on full body of work.
To me, either way, I want ISU to win. I'm not worried if pulling off some stunners like this might swing the coach-pendulum one way or another, especially since I can't directly control that.
I've been firmly in the "make a change" camp for (at minimum) two months. Let's pretend the team goes on an extreme miracle run, one that's implausible to expect but could come to pass with a lot of luck and perfect matchup situations. ISU wins the auto bid, goes to Sweet 16 as a 12 seed —*not only would that be a ton of fun, but if JP were bringing the coach back anyway, I wouldn't feel like puking — and I might have some anticipation going into next season.
However, if JP was still uncertain at this point, and he hoped for said miracle and then based his decision solely on that ... I still think that's putting too much weight on a 6- or 7-game string.
