The last two minutes were just one mistake after another:
LSH has to return the KO to get down to the two minute warning. The only excuse I see is that the KO went short (barely made the goal line) and then bounced like 10 feet in the air.
So the team gets a first down and puts the Pats in a bad spot. But on 1st and 10 the team loses 3 yards. No biggie. No gain on 2 nd down. No biggie. At this point on 3rd and 13, I either kneel, or maybe have Kolb run the boot (staying in bounds and getting down prior to contact). The odds of a running play going 13 yards there is very, very low.
In any event, RW should have been under instructions to go down if the first down wasn't there. No point in taking on a 255 lb MLB to get an extra 1/2 yard.
Fortunately, Belicek repaid the mistakes with the old "play for a 42 fg even though you are moving the ball" Do that, and you are begging for your kicker to gag
