- How reliable is this birthday data?
- Every birthday is labeled by source. Unlabeled birthdays have been cross-checked against two independent sources or come from an official league or team roster (each page names the site). Birthdays labeled “fan-submitted” come from a fan support application record, a single source that hasn’t been officially cross-checked; if you spot an error, email us. If we can’t find any verifiable source, we don’t list the birthday at all. We’d rather leave a gap than get it wrong.
