The fake FG was more coaching than execution. The players executed the called play (a FG block attempt). The coaches and players were completely unprepared for any other eventuality and reacted accordingly.
Agree to the extent that they blew contain. However, AJ Hawk has to stay as deep as the deepest receiver until Ryan crosses the line of scrimmage. If Hawk doesn't commit as soon as Ryan rolls out, at worst Ryan runs for a first down. Hawk messed up an assignment that high schoolers are taught.
