You have to be careful with McCarthy and his running numbers. He has previously expressed that the average per carry is paramount and bears watching. He has then said that the number of rushes is really telling and average isn't everything. He has also expressed the idea that he has to maintain an artificial balance anathema, because you have to be aware of the opponent, game situation and success rate.

Now he tells you he thought running it 20 times in the second half was a good target.

In McCarthy's defense, the team did have over 98 percent odds to win the game after Russell Wilson's fourth interception with about five minutes left in the game. Up until that point, McCarthy was fine.
First Half Runs: 16
Second Half Runs: 14

And that includes two drives, 6 plays with 5 runs, designed specifically to end the game and the last of those attempts was with less than 5 minutes on the clock. He wasn't run happy because of the target (see first half), but because he had the lead and a chance to close it out. He has done this before, many times. His end of game strategy needs a rethink, but its not a target number of runs that is the problem.

Its the drastic approach to milking the clock by running regardless of success rate or D alignment.

If I had to bet, that 20 carry figure is one of the common traits of winning teams that database divers pull out once in a while. It sounds impressive and a key to success until you realize that the reason all those carries came in the second half was because someone had a lead and were running our the clock. But that is not always the right approach.

And when he had to have a scoring drive in short order? They started winging the ball around again.
