The line might change quickly, but it's a live betting:
Quickly the reasons for UNDER are:
1) There were like 50 points in 1st Quarter, half of the 2nd quarter so far VERY LOW SCORING!
2) Line was 152 or something, so it's 10 points over the original line!
3) There is a clear favourite team in this match - meaning they should lead towards the end and run lots of garbage time.
I picked UNDER and placed £20 on it!
Goodluck !!!!
