Their last 2 meetings in Boston have totaled 210 & 223 points. LA enters this game off having paid out on TT Overs for both themselves & their opposition for 5 straight games (naturally 5-0 to Over for the fullgame total), while Boston is 4-1 to Over their last 5. That their last game between the 2 stunk offensively (170 odd points) was "because" it was in LA, "so it can be safely ignored".
Thats why the line is what it is. What have you done for me lately screams nothing but Over.
