What Zac has done that Marvin couldn't

[CKwi88]

I think Zac is standing on Marvin's shoulders in a way. There was a distinct culture change during Marvin's tenure, but he ran into a brick wall (playoff wins) for myriad reasons, both in and out of his control. Zac has, for reasons both in and out of his control, been able to break through.

If Zac got pulled through a time warp back to 2003 and was hired in Marvin's place, with the organization and players as they were, I'd be hard pressed to say that Zac would find that much more success.
