For those still worried about 'The Office' season 9, what with its ever-diminishing array of stars following the departure of James Spader, show-runner Paul Lieberstein, Mindy Kaling, and eventually the reduced presence of both B.J. Novak and Rainn Wilson, there's good news!  In addition to a finalized deal for Clark Duke to join the series, 'The Office' season 9 has just picked up yet another fresh-faced regular in actor Jake Lacy.  But, who will the former 'Better With You' star play?

TVLine is reporting that 'The Office' season 9 has picked up yet another new series regular, following its acquisition of 'Greek' and 'Kick-Ass' star Clark Duke.  Actor Jake Lacy ('Better With You') will fill the role of a new series regular at Dunder-Mifflin, though it's unclear what his role will be.  Lacy's casting marks a turnaround for the actor, having starred in the pilot episode of FOX's upcoming series 'The Goodwin Games,' before being replaced.

In addition to Lacy and Duke, Catherine Tate has been upgraded to series regular following her recurring stint in the eighth season.  Series leads Ed Helms and John Krasinski will in fact return, though likely sit out a few episodes to accommodate their burgeoning film careers.

Among the departed, Paul Lieberstein has stepped down as show-runner to prepare for Rainn Wilson's upcoming spin-off 'The Farm,' while Mindy Kaling will appear in the September 20 premiere (and possibly another episode down the line) before departing for her new FOX sitcom 'The Mindy Project.'  B.J. Novak has been downgraded to a recurring guest star, while season 8 star James Spader has departed entirely.

What say you?  Do you think 'The Office' season 9 is shaping up by undergoing a quasi-reboot, and casting new characters?  Do you think Jake Lacy can revitalize the stagnant series, or is it best left ending after this season?  Give us your take in the comments below!
