Did Mork & Mindy in a way, hurt Pam Dawber's career?

What I mean is that with all of Robin Williams' antics, all she could really do was react and just got stuck in that loop. In fairness, it was obvious right from the jump that Mork & Mindy was Robin Williams' show.

Her other big role is of course, My Sister Sam, which would've been all about forgotten (it only lasted two seasons) had it not been for the tragic circumstances surrounding her co-star Rebecca Shaeffer. I mean, was Pam when you get right down to it (and when not essentially there to be a straight-woman/foil for Robin Williams) charismatic enough to lead her own show?
