How Much Power Does ZT Have?

[THE PISTONS]

To summarize:

Lazor gets fired as OC in Miami because his offense is bad and ZT takes over and makes it WORSE.

Then at U of Cincy, he produces the 123rd ranked offense out of 128 teams.

And a bunch of people on the board think that Marvin was the problem with this team and that ZT is some coaching genius who is an obvious upgrade.
