I would tease both sides. You have a nice gap there with a bunch of nice #'s like 3, 4, 6, 7, 8, 10, & 11 there.
If you have to choose one side I'd choose Houston because I feel they do not only cover the +10 for the game but have a great shot in winning outright plus look at all the key #'s you get there at +15.
Dallas -1 sounds so easy but think how others felt who thought the same way about Tampa Bay.
