If you look at where the money is coming in, comparing different sites its roughly about 64% on Bolts
so line dropping is actually reverse line movement
they are trying to entice more money on Bolts with the smaller chalk and dissuade action on Stars by giving 5hittier odds
If your worried about odds not going up for Stars (It Will) then lock in a unit at +140 at several books.
If it goes up you can always hit it again later
and as a 3rd strategy you can hit it ingame after Bolts score 1st
this game is going to overtime, so that's yet another strategy, once game starts you can ingame Dallas to win in OT for some decent odds
