Dude once again.
Raye is being hamstrung by the QB. It's just THAT simple.
Sing calls Run or Pass, Raye has to send in plays that fit the personnel. Sing CAN override the play but with 25 seconds ticking off he doesn't have much wiggle room. So in the end they probably send in the original plays.
Some people act like there is no game clock and they can take their sweet time deciding what play to run if Sing is not enthused with Raye's selection.
It's the QB and has ALWAYS been the QB.
