Should I tail Rob Donaldson (@robdfb)?

TailSlips does not give betting advice. We track and grade public picks so you can decide based on a verified record instead of a claimed one. Rob Donaldson (@robdfb)'s full graded history is on their profile page, including the picks they did not win. Use it to inform your own decisions and bet responsibly.

How this record is calculated

This page reflects every publicly posted pick from @robdfb that declared a side, line where applicable, odds taken, and unit stake. Picks without those details are not gradeable and are not shown. Moneylines without posted odds are graded at the Pinnacle price from when they posted; spreads and totals default to -110. Player props without odds count toward win rate but not units profit.

Full rules at methodology. If you're @robdfb and you spot a genuine misattribution, email corrections@tailslips.com.
