Here’s what I have learned in the divisional games… The HC only matters a little bit.

Yes, QB is by far the most important position on the team, and to win the Super Bowl you need an above average, two dimensional QB, but it’s not hopeless. A great HC who can evaluate talent, motivate, and make good decisions can find a way to get a team into position to succeed and find the right QB.
I agree. The days of guys like Brad Johnson and Trent Dilfer, leading teams to the title are gone.

You need a dynamic, multi-faceted QB to go deep in the playoffs now.
