NO
in all totals - there is an advantage in betting the other way - UNDER. this is because most casual bettors simply play "favorite and over" all the time. how many of the "joe q. public" walk into a vegas sportsbook, go to the counter and simply bet Notre Dame every week - regardless of what the number is - and how many points they are laying? a LOT. they usually say something like, "are you kidding me, ND 'only' favored by 28 over Navy - they'll kill them - i'll lay the 28." so these people do that failing to realize this might be a "sandwich" game for the irish who only win by 21. the books know it so they inflate the total maybe a point and the fave's number about 1/2 a point, too (or maybe $.10 when this comes into play). over the long run it makes a difference.
i'm not saying only betting unders is the way to go - but if i had to bet only overs or unders - i'll take UNDER.
