They're basically saying we should win 3 games. Interestingly I think it was at 3.5 -110 at even juice. If I could see myself rooting against my team late in the season, I'd have put a large amount at under 3.5. Not the house though because miracles can and do happen in sports. Also, the players might be hyped to redeem themselves and play well despite the poor game plans and bad coaching. Sports gambling lines have trouble reflecting emotions such as redemption. This line at 2.5 with heavy juice is trying to draw in under betters. So it's like there was lotsa optimism they want to balance out. Vegas is very confident with that 3 win number
