That play was both an unnecessary risk and not utilizing or playing to our strengths. You have the shortest QB in the league playing in his second year throwing over and through huge linemen to a second string receiver on a timing play whose moving parts were a bit more sophisticated than need be. It was a horrible call given the circumstances and who and what it depended upon.
If you're going to do a pass play, you're best off faking a hand off to Lynch and giving RW, the slipperiest QB in the NFL at the time, a run/pass option, and if it's a pass it's to a receiver on a route where only they have a chance to catch it, and if the play breaks down you simply thro it away, not force it under any circumstance. The Hawks had plenty of pass plays on the chart with this basic concept in mind.
Or you just hand the ball to Lynch with the high probability he scores, and if he doesn't, you merely call timeout and organize two final plays.
Head coaches and their staffs are paid to know a lot more than us and to rehearse situations like this before they happen. Did the actually rehearse a situation like this and come up with this shyt play?
