Joseph registered eight points in the Penguins' last 18 games of the season.
Joseph managed just three points through his first 34 appearances this year, which included several stints in the press box as a healthy scratch before finding his game in mid-March while Ryan Graves (concussion) was sidelined. The 24-year-old Joseph's inconsistency could create problems when he and the Pens presumably try to finalize a new contract this offseason.
