All of it- this is HIS team, since he insists on playing GM. He could have signed or traded for another real threat at WR after giving Cooper away - he signed Washington for 1 million and banked on a guy coming back from an ACL injury. He could have traded for or signed a good run stuffing DT or 2 as well- but didn't. Those were two obvious holes we all knew about. A LB was needed too. Then he panicked and had to scramble to get Hankins and TY to try to cover those mistakes later on.
He seems content making the tons of $ he makes off sellouts at JerrysWorld, think it holds about 100,000 a game - as well as the merchandising $ he makes, Cowboys march is the top selling I believe. If the Cowboys somehow manage to ever win it all again, he just wants to make sure he gets the credit and glory for it - so nothing is going to change.
