That's because Football involves strategy, full contact, and playing to win. The Obama Syria circus involves people pointing and laughing at a fumbling chump.
Ah, so no one is allowed to criticize the President unless they are in his cabinet or actively participating in his initiatives?
You apparently don't understand that the president would need to be involved in something akin to a football game rather than a circus to have someone be a "Monday morning quarterback" for his dismal failures with Syria.
You can "Monday Morning Quarterback" anyone that is doing anything. Doesn't have to be a direct football analogy.
When I go to the circus it is to be entertained and there is no need to analyze the strategy & plays after the fact. With a football game many people breakdown the entire game and analyze the performance. A political fumble akin to a circus is simply a laughing stock for the world community - there is no "Monday night quarterbacking" needed for Obama's Syria performance.
