None. There is always so much luck involved.Percentage wise, I agree, but that's because the percentages are against everybody using that logic. 5 in 40 years is 12.5%
Izzo has 2 in around 24 years- 8%
Wright has 1 in around 23 years- 4%
Williams has 3 in 30 years- 10%
I don't think that's an accurate way to determine a coaches chances of winning a title. Tony Bennett is at 0%. What coach has a high percentage chance?
