I don’t believe Rizzi even has to generate wins. Aaron Glenn has zero wins or losses as a HC. It all comes down to familiarity and “looking beyond the results” with Loomis.
ML looking beyond the results, is why ive always thought that Rizzi (taking over if DA failed) was a trump card waiting to be played if all else failed. (I do not think that DA being fired was a reactive decision caused by the loss to Carolina)
