Pretty clear that Sitake blames last season on Ty. He wants to keep that message alive and well. So, Sitake is really saying: "My mistake was having TY over the offense and responsible for QB decisions." Only here, instead of going directly after Ty, he jabs at Tanner for not being mentally tough enough. Sure, that's all on Sitake. He just wants to single others out along the way. Great leadership, man. Gotta love it.
