I still see all his same stubborn tendencies, they just haven't bit us as often lately.
Serious question:. How many years is enough time without a championship, to realize it's time to move on? 10? 12? 15? How many coaches in history have ever won a Title if they didn't do it in their first 10 years at that program? Heck, same question for 5 years....maybe a few outliers, but I'd bet the vast majority of coaches who won a title at Program A, did it within 5 years of going there, and guarantee that is likely in the 99 percentile range if you look at 10 years.
At some point we have to accept, that better than the others since Lou just isn't good enough...10 years seems more than fair to me, considering no one else in our history ever got close to that much time.
