Monday Night Football...on buying 1.5 points -$1.50...taking the Favorite?

Taking Saints minus 3 It's not a good rule of thumb when wagering, but here in this match up, is it a worthy try? What are your thoughts?

Thanks

I'm not doing it and would not recommend for anyone to make the play either. I know of 1 guy guy who bet this.
