Boston - 4 1/2 in the 2nd half ??

[GOLDENGREEK]

Officials kept the hawks in the game ( lol - still down 15 ) with a 17-8 free throw line advantage

Celts with only 3 threes - Allen with 1 - Pierce with none


I see a 2nd half rout but why play the game basically at - 20 when I could have bet it at -14 1/2


thoughts ?
