During the crazy heights of the Eustachy era, LE would often start the post-game chat with Pete Taylor with some version of "celebrate night like this, because you never know when they will end".
Hiring Fred was a giant risk, but one that came up paid out far more than it didn't. Uncountable fun games in a short period, and a lifetime of "what-ifs".
Better to have had the time with him than not. Hopefully Prohm has similar or greater success, but perhaps he won't. Winning at this level is a difficult and volatile cocktail of talent, skill and luck. If it was easy to mix everyone would be doing it.
Embrace the good times, you never know when they will end.
