The thing to think about is 2 good qb's and both lose to GB in div round, what is the common denominator ??
Coaching !!
Romo takes the heat for only 2 playoff wins, during past 10 years, but again what is the common denominator ??
Garrett !! He has been OC and Asst HC, then HC / OC, then HC during the whole time Romo has been here
and put up great stats.
So just because Dak is young and looks promising, there is still the common denominator !!
The team was good enough to win and at least get to SB in 2014 and 2016 but get derailed by poor coaching in playoffs.
