did UNDER get killed last week?

[polson22]

i have noticed that UNDER has done really well this year, and had done very well with it. done poorly on ATS though (FYI)

anyway, following a guy who did really well with O/U. he seemed to have a consistent winning record this year and i think he had bias towards UNDER (and that's consistent. season good to UNDER, he has UNDER bias, he has consistent winning record).

anyway, i felt like UNDER was doing terribly last week early on so i backed off from further betting (miraculously ended up having small winning saturday but on tiny volume)... now i notice my O/U got absolutely killed last week after winning almost every week previous.

did UNDER get killed last week? (suppose i could spend 15 minutes and aggregate it, which i probably will).

also, is there some reason that OVER does better later in the year? it might make sense as offenses really start to click. and i know there are (were??) some really predictable reversals on ATS trends late in the year in the NFL (i don't play NFL so i can't remember what they are)

anyway, anyone else noticed OVER become good play late in season??
