Here are some pics from the All-22. Tell me who is open or even in a process of getting open at the top of Dak's drop. The receivers were still running and the QB had to hold on to the ball. This was what was going on most of the game. Dak should have just ran at this point instead of waiting because the OL wasn't going to hold up.
KM is doing what JG used to do with these long developing routes. These don't work when your OL is average at best and your WRs are terrible. This type of play is what got Romo killed.
