And given the jailbreak rush and low trajectory of a max range field goal (49 yards to kick, his longest is 52 yards), the kick gets blocked and run back for a touchdown. Best case, in a 7-3 game you are winning a battle of field position, and in missing you give the other team 7 yards and the ball closer to mid-field. The Giants did not capitalize on the next series, so many would say the call was not bad. It is a bad call if the kicker, who you may recall kicked the ball out of bounds after the touchdown, would have made the kick. But of course you are smarter than Belichick, ran these scenarios in your head and came up with more than "3 points good, 0 points bad. Me like 3 points. Losing by 3 points bad."
The fact is you are applying hindsight because if Brady makes that throw, you would obviously have to start a thread saying you were rock stupid for doubting the calls given all the similar successful fourth down calls ths season with 18 games of data. Again, if you are psychic and can disregard probabilities and capabilities of players and know definitively what plays work and don't work, contact the NFL as I am sure there is a job waiting for you as a coordinator or head coach. Otherwise, any garden variety fool can say after the fact is was a bad idea to call a particular play when it did not work.
