Interesting. So take a lead on the over expecting it will go to at least
125.5 -105 by Friday & then "lay the over" = play the under. I see the
opener was 124 so you are spot on re the direction this is heading.
My concern is it will cum back the other way & screw me, but trust
your judgement here.
Matchbook will have any market change so at worse a loss of vig and by lay, I mean at plus vig so you will be getting +105 on the under:drink:
You should pay around 5 cents a half point with NCAA totals, so to anwer your question that is OK. Not great but doable for me. In the long run I would bet the 1 number that is off and screw the other bet. The off number will win more than 53% of the time and make you money. That is is if the consensus total is 1.5 point different from the off number.
