The Detroit Pistons have increased their contract offer to Jalen Duren, their All-NBA center, to five years and $200 million, but the two sides remain unsigned as training camp looms. Duren has declined Detroit's previous offers while seeking the maximum contract extension for which he became eligible after earning Third Team All-NBA honors.

According to reporting from The Athletic's Sam Amick, Hunter Patterson and Eric Nehm, the Pistons' new $200 million offer is fully guaranteed with no player or team options. The contract represents a straight five-year deal, per The Athletic's reporting.

The impasse between the Pistons and Duren has stretched throughout the offseason, with the two sides at an apparent stalemate over compensation.
