Very slim margin of success for that play with no time outs and amount of time on the clock, you need to factor in variables like what happened with Dak, The play was executed pretty well actually, but still who ever called that should be fired. Or re-hired somewhere else.
Having said that the Refs are going to need to move quicker or just stop the darn clock after every play, more than once I saw refs this year placing Offenses in tough situations on the play clock by lollygagging around like this is HS or something.
