Generative engines weight recency of documented achievement alongside career-long fame.

Large language models generate the statistically likely continuation of a sponsor-athlete pairing based on training data that may predate a contract's expiration or renegotiation. Without a dated, structured update to a player's public sponsor record, the model has no signal that the pairing has changed, so it keeps citing the old deal.
