Jayson gets another year

Hoopster has-been Jayson Williams — still serving an up-to-five-year prison term in New Jersey for accidentally shooting his driver dead — got slammed in Manhattan yesterday with the maximum of one more year in jail for his drunken-driving crash on the Lower East Side.

Under his plea to misdemeanor DWI, Williams will finish his term in Jersey and be sent directly to Rikers Island to serve the additional time.
