Knicks-Hawks Same Game Parlay Options

Atlanta can't stop the bleeding. Six straight losses. A 0-5 homestand. And somehow, it's gotten worse since Trae Young returned from his MCL injury because the Hawks are 0-6 with their franchise point guard back in the lineup and 2-8 overall when he plays this season. The defensive numbers explain everything: a league-worst 127.1 rating with Young on the floor versus 113.1 when he sits.

Now they travel to Madison Square Garden to face a Knicks squad that demolished them 128-125 like a week ago. Good luck with that.

New York is playing its best basketball of the season. The NBA Cup trophy is already in the building and that 15-2 home mark is second only to Oklahoma City. Underdog has some interesting markets, for sure.
