Here are the stats since 2007 of the last days goals in the 12 games..
2012- 7 games over 2.5-33 goals-Avg of league 2.57..Avg of last game..2.75
2011- 9 over 2.5-38 goals-League Avg..2.73-Last game 3.16
2010-6 over 2.5-32 goals-League Avg 2.6 -Last game 2.6
2009- 8 over 2.5-33 goals-League avg 2.44-Last game 2.75
2008- 7 over 2.5-38 goals-League avg 2.52..Last game 3.16
2007-8 over 2.5-44 goals- League avg 2.61 ..Last game 3.66
So I would think if you would have bet all over at 2.5,worst you would have done is go .500 and lost the juice.
Better yet if you can find a total goals for all the 12 games at 7:45 AM Eastern Time, that might be better to wager on.Anything of say 32-33 the over might be a great play..
