well there you would be talking 7pt teasers at an average of -140 odds so your win rate would have to be 80% on those numbers...which it is not. A -3 fav covers the 6-pt teaser line only 69.4% of the time...-2.5 = 64.4%...those are horrible numbers. The key is to cross 3 and 7 as historically 24% of all NFL games land on 3 or 7 exactly, 4-6 approx 14% of time.I've seen some private analytical work by some really smart folks on teasing across 0 and how profitable it actually is....taking -3 to +4, etc.
yes it is. but when he was killing vegas with this the 6-pt teaser was +100 ... they moved it to -110 or even -120 at some places. 5dimes still has best teaser market around
