Having an all pro season doesnt mean much for any qb, if they are not also all pro once in the playoffs.
The problem with Dallas is they are good enough to win the division , and or make the playoffs,
but once in, the coaching, and how the players do is not good enough.
Dak is 1-2 in playoff games, not sure what his stats were in those games.
it isnt all on him though, the coaches and some of the other players, are at fault for losing those playoff games.
Garrett is 2-3 in playoffs. 2 WC wins so he is 0-3 in div round. Dak is 0-2 in div round.
Garrett was also 0-3 in the win and your in games during the 8-8 years.
Garrett was OC and play caller, back in 2007 and 2009 when cowboys made the playoffs, his offense scored 17 and 3 points
in the 2 losses. That isnt enough to win, and he had Romo back then, younger Romo!
So I see a common denominator in all this and it is Garrett.
