I am a bit confused with these type of bets? What does this -5 mean? Does it mean that Portland Trail Blazers will lose with more/less than 5 points margin? Sorry for such a silly question being a huge basketball fan, but I asked as I still don't know much about these terms... Also, please suggest me a site where I can get the best information, kind of basketball dictionary where each and every term about basketball is available...

One more personal question, are you yourself a basketball player at any National level?
