Don't know if anyone would have any trends on this, but I have had good success in second half O/U (particularly unders) where the two teams come out and score alot in the first half...say 21-10 at half (where the O/U for the game was only 42/43) and they play back to there trends in the second half. Last nights Cleve/Pitt good example 33 first half, 13 second. GB/Seat yesterday 34 first half, 14 second. Just a theory.
