I'd really, really, really hate to put myself at risk for endless ridicule here....
but lately I've been looking for NHL lines that are -200 ML or above and the O/U is 5 goals. I've been betting the overs, and it seems to be working well.
I've actually been betting games that are -200 or more. If the goal line is O/U 5.5, I take the under. If O/U is just 5, I take the over.
Anyway, carry on.
