FUN FACT - NY Rangers have not won a plus money game vs Southeast Divsion since Feb 15, 2007 - a span of 26 games.
They are overall 14-12 vs Southeast, but all 14 wins were as a lined favorite.
Humble opinion here is that NYR vs Southeast Division is most certainly going to be impossible to score relative (to the league as a whole) value on since the betting population in NYR's region is likely 10-20x that of any of those cheering for Southeast Division teams.
Such disparity likely does not exist as much when playing far more established NHL franchises such as the Northeast, the Atlantic and about a dozen of the western teams.
