I've been begging for them to run a gadget play.
Now IMO you shouldn't run a gadget play unless it's in an important time where it could put all (or most) the momentum in your favor. In other words if the offense isn't moving and you need a kick start... or to tie the game up... to take the lead.... or kick the flood gates open and kill the momentum of the other team by getting the point out of reach (or almost out of reach) for the other team to catch up.
Or right after the other team scores. There is almost nothing harder to watch... your team scratch and claw for a hard fought points... only for the other team to score a TD in the first four plays after it. It's even worse when the hard fought points was a FG and then the other team scores a TD. Talk about momentum killers....
But they shouldn't be running one every game... but at least 3 a year IMO. And the Packers did run one... they got Flynn in on the punting play as a blocker... and snapped the ball to him and he run for a first down. I like that play... but there needs to be a couple of more... I would like to see a Nelson or Jones pass...
