I wasn't in this thread through the game last night, and not going to go through it to see if my points are already posted. If they are my bad.
Shanny is a good OC, not so good of a HC. On 3rd and 4 in OT at the I think the 12 line or so, Shanny had to know that Spags was going to blitz, why oh why do you not either give the ball to your best player (#23) or run the QB.
The option to not defer in OT was the wrong call.
But the worst was not calling a TO with just seconds left in OT and seeing that the Chiefs were not going to kick the FG but go for the win. Why would you not call a TO then is beyond me.
