Of course not. Buzdar was purely for optics, nothing more. Just saw his press conference and others in PTI had to literally tell him what to say when media asked questions.
But PTI have formed committee who will support (control) CM, it consist of Pervez Elahi, Chaudhry Sarwar and Aleem Khan.
Honestly I'm not worried about Punjab CM. Imran Khan will be CM by default. PM doesn't have any power at all to control province after 18th amendment. For this reason he needed weak candidate for CM who he can control or throw out when ever he want.
Imran Khan himself will personally look after punjab.
