Totally wrong, IMO. You set a game plan,. but you must be willing to abandon it or change it depending on what your opposition has come up with to defend it.
And, if you dont, then you have been outcoached, and a loser of the game, UNLESS, as has been the case with the Pats on many occasions this year, that the defense has bailed out the inept offensive play calling.
A game plan , and the play calls, are only as good as the play caller himself.
You can have the greatest players in the world, and if they are dealt bad plays, lthey will never succeed.
Much like in poker, the greatest poker player in the woprld can never win if dealt bad cards. Sure, he may bluff a pot now and then, but overall, the cards will decide.
Same thing in football, the greatest players will fail if dealt bad plays. The plays will be the ultimate decider..Deal good ones, they win. Deal bad ones, they lose.
If you dont agree, lets discuss it.
