There were 4 minutes left.
We were 0/2 on 4th down in the game.
Webb threw a pick on the last drive, probably changing what their playcalling mindset was at that point in the game.
Those are the reasons i think they decided to punt. They felt their defense could stop them in 3 plays, force a punt, or get a turnover. They don't get the 2 yards, then we basically lose.
