They are in a two game winning streak, while the Knicks is coming from a lost.
And lately Nets are on a big resurgence specially that Durant is back + the newly acquired Curry and Drammond are doing good. While the Knicks are on a struggle although they have some wins. But they are still below at 12th spot. I think your bet is reasonable so good luck.
That's totally fine, we all have the same experience about betting in NBA or some other sports. Sometimes we lost and sometimes we win, that's normal because even if we analyze every stats and their performance in recent games, that won't be the assurance that our bets will go through as they're still humans that will make some mistakes along the way. Anyway, congratulations!
As for me, I lost the bet because spread was -3.5 for me and the Nets haven't covered it well, I'm just a point shy from that bet though
