So in this screenshot, am I betting NC State +5 at -171 odds?
Yes that is correct, you are betting on the other team (NC State) with a handicap of +5 at -171.

THANK YOU!
So would you say the fact that I clicked the "bet against +171" square and then an input box with odds -171 comes up. Wouldn't you say that's a bug or at the very least counter-intuitive? I don't get that at all!
I'll send you a private message, check your inbox. I got a table for you to understand the equivalencies .
