peteep- First, the 50 cent straddle on that prop is too much. Second, be careful on this one. The "no" seems like a nice plus but the "yes" should be about a -200 because the 3 scores in a row happens more often than you would think. In a game where the total is 45, there figures to be a lot of scoring making the 3 scores in a row even more of a possibility. Tough prop and not really much value either way. Pass.
I think the only time there might be an edge in that type of prop would be if you had two good defenses going up against two average or below average offenses then maybe the plus money on the "no" could be a play as scoring would be at a premium making 3 scores in a row less likely.
