Couple matches had a semi-swap where line moved for a moment to other side and then came back or where it was possible to select the +1 option at pinnacle with -110 odds. those are 1-2 so far. incl last nights Suns vs Jazz.
The main reason why these plays do good overall is because home factor is something that can easely ignored, the away team is often the better of the 2 and there is too much focus on the pure strainght of the teams. So it's easy to think the better team should win while home factor is often key in such matches. It will often turn out in a close match where home advantage comes trough when closing down a match while getting a +1 line instead of a -1 line which makes a huge difference in this scenario
