I originally thought that since much of the public generally leans to "overs" -- that it might be good to take "under" for the entire Grand Salami. I didn't have a source of historical data on this type of bet, so I started to collect data...
After just a short while, it appears that you can capture the statistical "tail" in some ways. In any given game, the current total of about 5.5 goals is a good over/under line for the total. However, there is a certain percentage of games that might be 8+ goal games (and even higher).
This seems like it can skew the results to the over side a bit (you can have a 10 goal game for instance at 6-4, but you can't have fewer than 1 goal in a game).
this play is also fun because you sort of have "action" on every NHL game that day... We'll keep an eye on this play...
