Ahhhh.....what the sports world loves so much......game 7's.  I imaging most think the home team wins most of them and is juiced for that fact....well let's see

Ignoring win order; considering site order: The team tied 3-games-all with Games 1-2 at home, Games 3-4 on the road, Game 5 at home, and Game 6 on the road (Boston) has the following best-of-7 playoff series and games record through the 2011 NBA and NHL Quarterfinals rounds:

Game 7 record, NHL only, all rounds: 80-53 (.602)
Game 7 record, NHL only, Semis round: 18-8 (.692)

So we are looking at a line of -145 for the game right now and you need a win % of 59.18 to break even for that lay.

So you are getting a very slight bonus by laying the -143 and a nice bounus if you go by the semis round record.

It's hard to go against a home team in game 7.  But considering there have been no OT games in the series, taking the regulation line of the B's +115 I think that is the way to go.
