He really had to thread a needle on that goal-line pass, and his guy (Adams??) never got his hands on the football. AR was a smidgen lucky that wasn't picked off.
The snap before, I think it was, I thought Rodgers might've been able to reach the corner of the end zone as he emerged from the scrum. Whichever Packers WR was engaged in that corner might've easily sealed off the defender to let 12 get in there. Improvise, go off-script, use your good legs to make something happen there.
One truism about Brady: If his coffin lid is even a bit open, you'd better slam it shut. In this case, you'd better not leave 4 points on the table by having to settle for a FG there.
By the way, all this is waaaay easy when analyzing from the Barcalounger. LOL.
