This Is Also Completely Wrong

Same article:

Will Rob Gronkowski score a touchdown?
Yes: -160
No: +140

Will Rob Gronkowski score a touchdown in the first half?
Yes: +175
No: -200

These two bets, taken together, are a very weird mix. The given likelihood of Gronkowski scoring a touchdown in the first half is just 35.3 percent, but his odds of scoring a touchdown in the game are at 59.6 percent. Those two numbers imply that Gronkowski will score in the second half about 92.1 percent of the time, and that a bet on Gronkowski not scoring in the second half would have true odds of about +1166 or so. I hope somebody offers that.

I have no idea. 92.1%? I don't know, man.

Eighth(?) grade probability time!

The setup:

The math:

.647 * x = .404
x = .624
1-x = .376

The result:

So illogical!!!!

Doing the math wrong...whatever. But doing the math wrong, getting an answer that MAKES NO SENSE, assuming you are correct, and just going with it? And if those two lines were truly implying something insane for the 2H, wouldn't one side of the 1H or FG line have to be way off, too? So...maybe look into that?

How Not To Handicap A Prop Bet

I still can't believe Barnwell actually wrote this:

What will the jersey number be of the first player to score a touchdown?
Over 80.5: EVEN
Under 80.5: -120

Few things have made me question my life decisions more than putting together a spreadsheet to answer this question. But I did it, taking every player who has scored for these two teams this year, removing guys who aren't going to play on Sunday, adjusting for the games they played in and missed. It was so fucking stupid on so many levels. But I did it. And in the end, I got an expected number of … 64.4. Great, so an offensive lineman is likely to score on Sunday! In reality, it just suggests that the running backs for the teams are likely a little undervalued here, and that logic only goes further with a possibly-limited Gronkowski (number 87). Go under here, but realize that we're all losers for playing.

I have no interest in legitimately handicapping this (I guess that makes two of us), so I just adjusted the numbers for people listed at Pinny to make them fit to "an expected number of ... 64.4":

As noted, the weighted average of these is 64.4. Based on this information, Bill Barnwell recommended the under. Hopefully the reason that this is horrendous analysis is really obvious.

If you do this really sophisticated thing called adding, however, you get 48.5% for the under. With the exact same data set. With a line of -120. So an ROI of -11.1%. Sometimes referred to as lighting money on fire. While, based on that same (made up) data, the other side is +EV, with a 51.5% bet being offered at +100.

I don't really have a point to close with here, so:

The Most Ridiculous Super Bowl XLVI Props

Fifth annual, and still going strong(?). Here we go:

Who will win the Super Bowl XLVI Coin Toss?

SportsBetting:
Giants, +102
Patriots, +102

What will be the result of Super Bowl XLVI Coin Toss?

SportsBetting:
Heads, +102
Tails, +102

Not quite as good as last year, but this is still one of my favorites.

Will Gisele Bundchen be shown on TB during the game?
From kickoff to final whistle, live pictures only, halftime does not count.

Bodog:
Yes, -160
No, +120

5Dimes:
Yes, -215
No, +165

Arb! I tried to research this one but gave up after finding a fake Gisele Super Bowl blog and discovering that she is supposedly on her way to becoming very, very wealthy.

I went with "Yes, -160" at Bodog, which I cannot back up with math.

Who will be shown first?

SportsBetting:
Giselle Bundchen, -125
Abby Manning, -105

SportsInteraction
Giselle Bundchen, -120
Abby Manning, -120

I don't get why Giselle isn't favored by more; isn't she a LOT more famous than Eli's wife?

Who will the MVP thank first?

This one is the best. Sportsbook also has the same prop for winning coach rather than MVP, and is offering "Does Not Thank Anyone" at +800. My unofficial summary from the last four years:

Last year some books graded it as Rodgers thanking the defense (teammates), and some graded "Does Not Thank Anyone" as a winner since he didn't say the word "thank". Either way, +250 continues to be a great price, available across the board.

Color of Gatorade dumped on winning coach?

Not sure about this one. It's been orange the last two years, but yellow and clear the two before that; Stockle Mon has a more extensive summary. Since it was clear/water the last time each of these teams won and four of the last nine dumps, that seems like the best pick here if you can get the +215.

Will Kelly Clarkson omit/forget a word of the National Anthem?

5Dimes:
Yes, +700
No, -1500

Bodog:
Yes, +300

Inspired by last year's mishap. No real opinion here; if anything I'd take the +700 at 5D, but probably just stay away.

How long will it take Kelly Clarkson to sing the National Anthem?

5Dimes:
Over 1:34, +100
Under 1:34, -140

Sportsbook:
Over 1:35, -115
Under 1:35, -115

Bodog:
Over 1:34, -120
Under 1:34, -120

SportsInteraction:
Over 134.5, -115
Under 134.5, -125

Stockle Mon has also researched this one quite a bit (good work!), and it doesn't seem like there's much of an edge. So, when in doubt, line shop. Here is my completely-made-up estimate of the probability of the total time being within each second:
The thought behind the skew was that 1:34 is a pretty low time, so there's more room to go way higher than way lower.

That was an unbelievable waste of time, but it does allow me to see if a middle might be worthwhile:

That's assuming the 5Dimes line is efficient (which is not true at all), but you can shift the graph around a bit and you still come out ahead, so I went for the O1:34/U1:35 middle.

Which city will receive a higher TV ratings (market share)?

Bodog:
Boston -7, -120
New York +7, -120

Reader Will W. recommended this one, noting that he laid the chalk. Wikipedia tells us that Boston won by 14 four years ago (81-67), although it seems possible that was a bit inflated since the Pats were 18-0.

There are also a bunch of props on what Madonna will wear/do at halftime, but I don't have much to add to those.
