I've put all the stats into my spreadsheet to determine the score of all the divisional round games for this weekend. After doing so, I've placed a bet on one of the games.
The system has Dallas and Green Bay going to a tie. Whenever it does this, the rule of thumb is to go with the underdogs.
Green Bay are the underdogs. The bookies have them getting four-and-a-half points. That's good enough for me! In my opinion, if they're going to be underdogs, they should be +3.
It's a great line.
