Mike McCarthy missed an opportunity Monday night.
With the score tied at 17 and 1:44 on the clock, the Bears managed to earn a 1st and goal from the 9. The Packers had only one timeout, so CHI could run nearly out the clock and kick a field goal if they chose. FGs from that range are successful about 94% of the time, and with the good conditions, it's probably even higher.
Had CHI scored a TD on 1st down, that puts GB down by 7 with 1:40 to go, which gives the average team about a 10% chance of winning. A FG attempt after 3 clock-burning runs, gives GB almost no chance to win. GB's only hope would be to prevent a TD on 3 straight downs and hope a FG misses.
Depending on which down a possible TD might occur, the WP for trying to stop the score is less then 0.03. A FG misses 6% of the time, which could lead to a tie at best at the expiration of regulation time. Assuming a 50/50 chance in OT, that's 0.06 * 0.5 = 0.03.
By not allowing CHI to score the TD on 1st down, McCarthy cut his chances of winning from about 10% to about 3%. Neither prospect is very appealing, but every little bit matters
