Please. Give me a break. I am not assuming that Eichorst made the call. I am only pointing out that nobody knows who made the call. MR is a possible. Devaney is a possible. Eichorst is a possible....and it could have been a group decision where all 3 reached a consensus that Banker needed to go and that Diaco would be the best replacement.
It is not important to know who made the decision or how it was made, but I think it is important for everyone to understand that nobody knows who made the decision and that it is wrong to assume that MR made it.
If I had to bet, my guess would be that Devaney came up with the idea of replacing Banker with Diaco. IMO, Devaney would be aware of great coaches on the market moreso than Eichorst or Riley would be. SE and MR have other things to keep them busy. Being aware of good coaches on the market and measuring the performance of current coaches would be exactly in line with Billy Devaney's duties.
Devaney could have presented his report card on Banker to Eichorst, measuring defensive performance, recruiting, and unit morale. Devaney sells Eichorst on the idea that Banker is not cutting it and that Diaco is an intriging replacement possibility. Devaney convinces Eichorst that Diaco is a SE type of guy...the opposite of an energy vampire...a true energy hero.
Devaney and Eichorst finally agree that replacing Banker with Diaco would be a good move and they both approach Riley. Although Riley has never heard of Bob Diaco, Devaney gives Riley his background and Riley concedes that it would be a good move and then all three move forward to make it happen. As soon as Diaco agrees to come to UNL, Riley calls Banker with the news. SE & Devaney let Riley make the announcement because it looks best if it appears it was the HCes idea.
Yep, that would be my best guess of how it went down. Is it weird science? Something like aliens built the pyramids? I don't think so.
