Overthrow was Stanley alone, no denying that, but the goal-line pick was a circus of F-ups:
Render snaps the ball before Stanley is ready
Almost nobody is set, most visibily the right side of the OL is standing up looking around, which should have been illegal procedure
Fant is looking at Easley trying to relay the play call, but Easley already knows and Fant gets left standing flat-footed rather than blocking his man
Stanley tries to hurry a playcall rather than getting a timeout and makes the correct read, but the throw is too high
Kirk is running onto the field late trying to get a timeout
One of the back judges SEES Kirk asking for a timeout, goes to blow the play dead, and then swallows his whistle
It's almost impressive how bad things truly went on that play.
