Gilesfan, if you are an advantage gambler and its possible you are from reading this thread, you should see that arguing over bought points in college basketball is clearly a - EV play for you. Razor Ramon Monarch is arguing that his small sample size of buying points proves its worth it. At this point why even have the conversation?
The only question to ask yourself is do I gain an expected value when adding a half point to cover the extra 10 cents of vig I am charged. In all #s for CBB the answer is no. The 3 is breakeven to buy off of.
I am sure Razor has looked at historical data for college basketball to make his decisions but someone out there took a few seasons of data and played around with it.

On top of empirical evidence that shows it's a losing proposition, how about the common sense one. If it is something that is profitable why would the sportsbook allow you to do it so easily?
If Razor is up a ton of money this year its cause the games he selected are winning, most importantly. If enough games are winning instead of losing on the bought points to overcome the extra juice, its short term variance and wont last forever.
There are a few instances in CBB, CFB and NFL where buying points makes sense. I'll list those here.
CBB
Buying off the 3 is breakeven so it won't hurt you either way. Everything else is a waste.
NFL
- Buying on/off the 3 is worth about 23 cents, so if you can pay 20, go for it.
- Buying on/off the 7 is worth about 12-13 cents, so if you can pay 10, go for it.
- The 10 is worth close to 10 cents, so it's roughly neutral in terms of EV if you want to buy the hook.
- Also, in totals, the 37 is worth right around 10 cents, so you may actually want to buy on/off the 37, but that's the only total I'm aware of.
CFB
- I'm less familiar with the exact values here, but it's worth slightly more than 10 cents to buy on/off the 3 or 7, so if you can pay 10 for either number, go for it.
NOTE: Make sure you're making the correct comparisons when deciding whether to buy points or not. If you have a reduced vig out (-105 or less) and you can get something like an NFL team +7 -105, you'd need to be able to find +7 -117 or so to make the half-point buy worthwhile. Even though you may be paying 10 cents more at a full vig shop, +7.5 -120 is inferior to +7 -105 b/c you're actually paying 15 cents. This may sound like common sense, but it's not always apparent to some beginning/recreational gamblers.
Thats about all the - EV time I'm willing to give to this. I'm sure everyone else ready to let it die too. For some reason I had to slam my head against the brick wall a few times too. Carry on. RIP Blaine. We will miss your thong in Richmond on Fridays.
