There is a lot of assuming going on here and you know what they say about assuming....
Pretty easy to critique a game plan after the game is over. Pretty tough to know what the game plan was if you weren't there. Think back to your playing days...did the teams you were on execute every game plan to perfection? If not should your coach have been fired?
Here is a quote I like for times like this: "It is not the critic who counts; not the man who points out how the strong man stumbles, or where the doer of deeds could have done them better. The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood; who strives valiantly; who errs, who comes short again and again, because there is no effort without error and shortcoming; but who does actually strive to do the deeds; who knows great enthusiasms, the great devotions; who spends himself in a worthy cause; who at the best knows in the end the triumph of high achievement, and who at the worst, if he fails, at least fails while daring greatly, so that his place shall never be with those cold and timid souls who neither know victory nor defeat." - Teddy Roosevelt
