Philly Union for sure, they've been selling homegrowns to Europe like it's a business model lol. If you're betting on future stars, their pipeline is basically a cheat code.
Honestly the wildest one for me was a live bet on a random tennis match where the guy was down a set and 0-5, somehow came back and won the whole thing. Odds were like 200x, still chasing that high tbh.
