your totally right and I knew that. I am pretty sure the book know this adapt to it. Thanks.
Just like in MLB, the preseason saw weak lines like -110 to -130 for heaviest favorites. The books just couldn't adapt all too much even if an underdog team still has same nucleus from the previous year, due to less action & unpredictability of the preseason games.
So I can imagine it'd be similar with teasers for NFL preseason. In fact, one of my most successful bets last season was a 4-pick 13-point (-120) teaser on the AFC & NFC championship games (sides & totals). Someone made the argument how the lines are already tight & accurate by that late point in the playoffs that it was unlikely to see a lopsided result in either game. Of course, anything could have happened in a conference championship game, but anyway, I only made a couple of teasers all year last fall but that AFC/NFC 13-point teaser was a jackpot for me for that day.
Back to the NFL preseason... I'm not so sure we won't see 27-7 games lost by a +4 dog (so even teased 14 points wouldn't do the job). However, for preseason, I would rather add the extra teaser points to a DOG than a favorite since it's still too early to make strong lines on the favorites (i.e. -9 favs probably won't be found in preseason? Not sure?). I suspect it's because not many games would really result in a 20-point win margin. Just a wild guess.
