Right. You're assuming he cannot be successful if he has not been after 5 years. Why?
I am generally in favor of cutting bait if the writing is on the wall, which is why I qualified my position by saying if he's winning 2 or 3 games a year, that changes things. But, short of the bottom falling out, I see little to no risk of just letting him have it for a decade. We have always been bad-to-mediocre (with anomalous excursions to pretty good). Like for 130+ years. Giving him until 2031 would be 5 years extra. What is 5 years in the big picture? If it doesn't end up working, we'll hire someone else and probably be right about where we always have been.
Because the 5 years shows you what type of coach he is.
You use terms like "bottom falling out." What does that really mean though? Does a losing season, much less consecutive losing sesons fir that description?
I said this before, people are really talking about different things, imo. 6-8 wins a year was thrown out, and I can see an argument for sticking with that. I don't agree, but I see the merits of the argument.
More than one losing season, and I have to wonder why people would argue to keep that around. Especially if the better years were at the beginning.
