stay away from teasers in Week 1: Basic strategy 6 point teasers are 61.1% (well below the 72.4% at -110 required to at least break even) in Week 1 the past 12 years.
here were the line moves and results ATS for Week 1 last year, teasers got crushed
Not saying it happens again this year, just that it makes sense to me that the variance/volatility in Week 1 is higher, and so teaser performance would suffer.
