The secret to anticipated national tv games is to always bet on the opposite of the obvious outcome and the narratives.
The obvious is that the dominant Lakers are riding high and everyone expects them to beat the Knicks who just can't beat good teams at all, that's the storyline on them. And the line being only -3.5 is begging you to fall for the trap and take the Lakers. We've seen this a million times before.
Knicks +136 to finally beat a good team on TNT.
