What do you mean Shanahan hasn't advanced any further in the playoffs than Turner? 2005 AFC Championship Game down? Shanahan has gotten further in the past 3 years than Turner has at any point in his entire career. And why are we arbitrarily picking the past 9 years? Over the past one year, Turner has advanced further in the playoffs than Bill Cowher. Over the past two years, he's advanced further in the playoffs than Andy Reid. You gonna make the case that he has a better postseason resume than either of those notables, too?
Shanahan has two superbowl championships, two superbowl appearances, three AFCCG appearances, four divisional round appearances, and seven wildcard appearances in 14 years as a coach. Turner has 0 superbowl championships, 0 superbowl appearances, 0 League Championship appearances, two divisional round appearances, and two wildcard appearances in 10 years as a coach. Even if you do want to arbitrarily pick whatever window makes your point look not quite as asinine as it really is, you can compare Shanahan's postseason record over the past 9 years and it still blows out Turner's career postseason record. 1 AFCCG appearance, 1 divisional appearance, 4 wildcard appearances in 9 years trumps 0 AFCCG appearances, 2 divisional appearances, and 2 wildcard appearances in 10 years no matter how you slice it.
