...except for one thing: quality of product.

Surely MLB and NBA are 6-7 days a week, but, in baseball, you can watch 2 teams play a double header and see roughly the same quality of play in back to back games. The NBA doesn't play double headers, but you can see the same quality of play from one day to the other, or every 2 days.

In football, in overtime play doesn't look as good as the previous 4 quarters. The toll it takes to play football is not something players can recover from one day to the other. Case and point, Thursday Night Football.

It is not only the physical aspect of it, is the planning and logistics of it.
NBA= 5 players on the floor, 5 positions, and more or less everyone on the floor could play any position if need be.
MLB = 9 players on the field, 9 positions, I'd argue that other than pitcher, catcher, and shortstop (maybe 3rd base) the rest of the positions any player can play it if need be.
NFL= 11 players on the field, all highly specialized, 3 distinctive units. Some positions, you may interchange, like a TE can play FB or vice versa, or a RG may be able to play C or LG, but overall, it is very defined not only by position but by body type.

So give an NFL team less time between games, it results in bad play because of the lack of time to prepare and heal from the previous games.

Of course, there's the extra days a team gets after playing on Thursday, but that does not compensate from what happened the previous week. See Saints playing home against a very physical Whiner team then having to travel to Atlanta on Thursday Night and Drew's TD streak coming to an end.

'Cause the simple man pays the thrills, the bills and the pills that kill
