On paper, you can score .25
A few years back, in an inspired moment of selfishness and attempted parenting, Homer Simpson introduced his daughter, Lisa, to the exciting world of sports gambling. Homer’s reasoning for why he gambled was that it put the “icing on the cake” and made the games more fun to watch. Homer may be an American icon for stupidity and poor parenting, but in this case, boy was he right. Whether you are doing pick ‘em games online, betting among friends, or gambling Grandma’s farm at Vegas, adding the line and the spread to a game makes it more fun to watch.
For example, last year, I remember watching the Arkansas v. Florida game, as time was winding down, I found myself celebrating like an idiot after Florida turned what was meant to be a short yardage, drive extending run into something like a 30-yard gainer to beat the spread. The year before, I was praying Navy v. Notre Dame would go into double over time to force the winning team to win by 8 and therefore cover the 7.5 spread.
Everyone has their own system for making bets and picks. For some people its gut, others experience, and others still, which team has the cuter mascot. For me personally, looking at the spread in isolation doesn’t really tell me anything. Let’s take for example the marquee match-up this week: Texas @ Oklahoma State where Texas is favored by 8.5. By itself, 8.5 is kind of a weird number isn’t it. What is that? A touchdown, a 2-pt conversion, and missed extra-point by OSU? Three field-goals? A touchdown, PAT, and field-goal? Depending on how you interpret that 8.5 you could get to a bunch of different places.
Thankfully, Las Vegas gives us some insights into their infinite sports wisdom by also providing us with the over/under line for the week as well. In the case of Texas @ Oklahoma State, the over/under line is currently 52. A common mistake people make is just taking the over/under line and dividing it in half, and adding the 8.5 to it. This is wrong.
If we took 52 and divided it in half, we would have 26 and 26. If we add the 8.5 to one side, we have a score of 34.5 to 26. The problem is that 26+26+8.5 =60.5. In that case, we are giving Texas a lot more credit than Vegas is.
To do this right, you take the over/under line and divide it in half like we did before. So right now, the score is 26 to 26. We then take the spread and divide IT in half as well so we get 4.25 and 4.25. We then ADD 4.25 to Texas because they are favored, and we SUBTRACT 4.25 from Oklahoma State since they are expected to lose. The result, then, is that Las Vegas believes the score of the Texas @ Oklahoma State game is 30.25 Texas, 21.75 Oklahoma State.
So now we have to ask ourselves two questions:
1. Do I think Texas can hang more than 30 on Oklahoma State?
2. Do I think Oklahoma State will put up less than 22 on Texas?
At least now we have a score to react to. Does 30-22 sound compelling? If so, Cowboy up. If you believe in Colt McCoy (a man whose very name screams “Texas”) and you fear the Texas defense, then “Hook ‘em Horns.”
For those of us who like to go the extra mile, you can go to http://www.cfbstats.com and check to see whether this makes sense based on the average PPG both teams put up. If you are like me, will find yourself Saturday morning with a pick sheet in one hand and a beer in the other at tailgate, at least you have something better to react to than just a number in isolation.
