NBA Teasers - Where's the EV

[kaboshedx]

Hi All,

So I've been following these NFL wong teasers and see why it is +EV when the tease crosses the 3 or 7 points mark.

But where does the +EV lie in basketball teasers? I usually will tease a favorite down to a pick 'em, is this a good strategy? I guess the answer to my question would be the old "if you thing your pick will win but has less of a chance of covering"...but is it this simple or are there some stats that should be taken into consideration when teasing NBA games?
