OK, let's leave the 80 yard run in the equation. So we have a 1 in 16 chance of running 80 yards and a 15 in 16 chance of running 2.7 yards. If we happen to get the 80 yard run (ok, 27) then we score right away and the Giants have too much time remaining just like the pass everyone is b!tching about!
Let's try to figure out the best possible scenario: we run the ball on every down and gain just enough for the first down each time. There's 4:10 remaining from the 27 and we can run at most 35 seconds off the clock. After 3 downs we run off 1:45 so 1st down at the 16 with 2:25 remaining. After first down you're at the 12 and at the 2 minute warning. The next play you're at the 9, the Giants call time out with 1:55 remaining. 2nd we're at the 5 with 1:50 remaining and the Giants use their last timeout. At this point we HAVE to get the first down at the 2 or we kick the field goal with about 1:20 remaining. If we get the first down (and don't score a touchdown) we kneel a couple times and kick the field goal. So theoretically we could've run the clock out on a last second field goal.
The problem is, 1) there is no guarantee we could run that effectively (and in the latter part of the game we couldn't), and 2) everything would have to go right (including not gaining too many yards on a play and getting a first down before running 3 plays).
Personally I liked the call. I was so sick and tired of Jauronball (playing not to lose). Fitz made a bad pass. If it was good we get the touchdown and the Giants have 4 minutes to TIE THE GAME. Guess what, they might leave us some time to get into field goal range. To me we could play this "what if" game forever (and we probably will for at least the next 2 weeks ) but I'd rather be agressive and play to win rather than sit back and play not to lose. Its just what winning teams do.
