looks like good stuff but its not exactly what i was looking for. Lets see if i can explain it better.
credentials
1) home team is favored by 8 or more points
2) home team is down at half time
3) second half line makes the home team a favorite of less then 3 points for the whole game. (so the home team is down a decent amount at half, more then a point or two)
4) home team covers the second half spread
I didn't check all the games you just put up, but the one i checked was Sac @ Bos. Boston was a -15 for the game and was down 1 point at half. The second half line probably put boston around -10 for the game, which doesn't fit the criterion. Thanks for the help
