Sorry in advance if this has been discussed before, but I didn't see it in the FAQ.

I've been browsing this forum and looking at different lines for Sunday's NFL action and I was wondering if I have a +EV opportunity. There are actually a few of these but here's one example.

Tampa Bay is playing at New Orleans Sunday. Site A is offering +110 to take TB +3. Site B is offering +104 to take NO -3.5. Would it be profitable to bet both of these? Will the game end with the favorite winning by exactly 3 enough to make this a losing scenario? There's other games that have these lines too, some with even money for one team and +1xx for another. However, all of them would fall on the key numbers; 3, 4, 6, or 7 point wins by the favorite would make me a loser.

Any insight would be appreciated and if anyone knows how this applies to basketball or other sports I'd be interested in that as well. Thanks.
