So the 68% was based on one year's playoff results.
Kubiak's average record per season is 8.4 wins and 7.6 losses. His Texans average a 2.5 finish in a 4 team division. I question the 68% value. It looks more like 50% to me.
You will offer an opinion on Kubes as a coach, but you leave evaluating player talent to the experts. Hard to have a discussion about our opinions if our opinions are rejected because we aren't experts.
