Interesting premise. I took a quick look at some stats to see if they show much difference, comparing Thursday games, to Sunday games, to Monday games.I limited it to weeks 10-16 (the weeks there are Thursday games) so the seasonal weather is equal. I eliminated overtime games because only Sunday had any and so they had extra time to accumulate stats.Passing yards is team gross passing yards, so like our fantasy passing yards does not have sack yards subtracted as normal team passing stats do.Passing averages:Thursday: 223.6ypg, 1.1 TDs, 0.9 Ints, 2.8 times sacked.Monday: 277.4ypg, 1.7 TDS, 0.9 Ints, 1.7 times sacked.Sunday: 282.5ypg, 1.4 TDs, 1.0 Ints, 2.0 times sacked.Rushing averages:Thursday: 112.9ypg on 27.4 carries with 0.5 TDs.Monday: 118.8ypg on 26.6 carries with 0.9 TDs.Sunday: 143.6ypg on 31.4 carries with 1.1 TDs.Thursday sees a big drop off in passing yards and increase in number of times sacked. Rushing yards and TDs also drop off for Thursday. MNF see rushing yards drop as well. Then I eyeballed the teams to see if scheduling might be having an effect. Just eyeballing the Thursday vs Monday night I don't see a glaring difference with the bad teams who played. Both have about 20% of the NFl cellar dwellers as participants.But, the Monday night matchups have a lot higher percentage of the potent passing offenses. Thursday's 18 participating teams contained 5 appearances by top 8 passing offenses, or 29%. Monday night, 7 out of 14 participating teams were top 8 passing offenses. So fully 50% of MNF participants were potent passing offenses. So that would probably be a big contributing factor.
