Sounds like you have been mislead to believe teasers are not profitable if not very much preferred. If you lost on teasers in the past then it's probably due to poor selective choices. When you asked me why -.5 instead of
-6.5 leads me to believe you made some serious errors on teaser selections in the past. Parlays are the betters demise. Many more teasers are actually won then parlays. Parlays are by far a losing proposition but then again I have only been doing this for the better part of 10-12 yrs. Teasers have not been around that long but parlays have and believe me I used to lose a lot of money playing parlays before getting turned onto teasers. You asked why LSU -.5 instead of -6.5? That question makes no sense but I will try to interpret the point of a 3 team teaser as opposed to a 2 team teaser in this situation. First of all there is no way possible to tease LSU down to -6.5 or obtain a parlay with LSU -6.5 since the line is -10.5. Second you miss the opportunity if LSU wins by 1,3, or4 then you lose the whole teaser situation as opposed to LSU -.5 which wins in any of the previous examples. Also a 2 team teaser -6 or -7 pts is not viable because your left with MU -20 or -19 whichever the case you still lose if the spread hits those panic numbers 20,21, or 24. With MU -16 I'm absolutely 100% positive they will cover even with a bad performance. The least amount MU will cover by 17 pts. or better. The same theory holds true for Boise St. -22. If you only take them in a 2 team teaser your left with -16 or -15 and lose out on crucial numbers if Boise only wins by 13 or 14 pts. Again, if Boise has an off day I'm 100% sure they will cover the 12 pts. but not 100% sure they could cover a 13 or 14 pt. spread. The third team was the only difficult choice and decided to select LSU based on a previous post that I stated defense, revenge, and the fact that all LSU has to do is win at home to bring home the $$$. Clear as mud, right? As somebody above stated Arkansas could outright win the ballgame which has me thinking about a different third team like W. Virg possibly. I'll have to research this more throughout the week. Hope I clarified the matter for you.
