it's too early in the year for this shyt
But since Grunwald was just a figure-head and really didn't have any control over any decisions, I don't see what the issue is
One issue is that Mills is a crony...he was shuffling the Knicks through the Anucha Brown-Sanders/Isiah mess (threatening her job if she reported harassment) and he's mostly a money guy (Marketing experience, not much personnel stuff).
GG had enough success with the shyt shop he was handed. I would say the same for Walsh too, actually, and anyone who's brought max guys in (TRUE franchise max guys) under Dolan. The players think he's good for lining their pockets but they know the Knick organization is terrible and there's no chance to win. NO OTHER TEAM would touch Amar'e with uninsured knees and Walsh dug into the scrap heap for him b/c it was the only option we had and Dolan was just itching to throw money at someone.
The issue is we don't reward smart personnel moves and creativity like the Spurs, Rockets, Thunder, Nets, Warriors... We punish people who do their jobs well by making them fear for their jobs tomorrow. Have you ever worked in a company like that? It's a terrible way to build. That's why we haven't built much but playoff exits and overpaid teams.
