# You Don't Know Ball

> Source: [You Don't Know Ball](https://youtube.com/watch?v=uRUl_HqgGFo)

## Summary

The video argues that relying on 'ball knowledge'—intuition and matchup analysis—makes you a worse sports bettor. The creator shares his personal experience of making no money for two years using this approach, then turning profitable by strictly following mathematical models and line shopping across sportsbooks. He emphasizes that books already price in public knowledge, so the only edge is finding discrepancies in odds.

### Key Points

- **Ball knowledge hurts betting** [00:01] — Using intuition and expected outcomes led to no profit for 2 years, earning only $18 across PrizePicks, Sleeper, and Underdog.
- **Math-based betting works** [00:13] — After switching to following the math without personal bias, the creator's returns increased by about 26%.
- **Books price in public info** [00:27] — Cappers' advice about matchups or team tendencies is already reflected in the odds, so it provides no edge.
- **Example: Wemby over PRA** [00:40] — Wemby over PRA 42.5 is offered at -128 on FanDuel, 43.5 on softer books, and -119 on PrizePicks, showing line discrepancies.
- **Shut off your brain** [00:55] — Stop relying on opinions or perceived edges; follow the math to win long-term in DFS.
- **Beware of cappers** [01:07] — Anyone selling picks or Discord subscriptions likely doesn't have a real edge.

### Conclusion

The only sustainable way to profit in sports betting and DFS is to ignore subjective opinions and strictly follow mathematical models and line shopping.

## Transcript

ball knowledge will make you an infinitely worse sports better. And you can see the proof here. For 2 years basically, I was using ball knowledge and things I thought would happen, and I made essentially no money. I mean, in 2
years I was at about $18. This is for PrizePicks, Sleeper, and Underdog, so that I started following the math and didn't care if I thought something was going to happen or not, and just started following the math, we're up about 26%
why you shouldn't listen to any cappers who say, "Oh, this guy's got a good matchup. This team gives up the most threes." Whatever it might be, because the books already have that priced in. So, that's why I started only looking at
the math. For example here, we have Wemby over PRA 42.5. Well, on Underdog, see over on FanDuel, which is fairly sharp for player props, you get this at minus 128. A bunch of these softer books have it at 43.5, and then PrizePicks has
it at minus 119. So, you need to simply just shut off your brain, stop thinking about what you think is going to happen, or what matchups you think you've got an inside edge on, and just follow the math. That is truly the only way to come
out on top in the long run, especially with DFS. Anyone who's telling you otherwise is probably trying to sell you their Discord with paid picks.
