What would mediocrity look like to you? Seriously what would you realistically done with the roster? Be realistic...
So how exactly would you judge a gm that turned over an entire roster and went through 3 coaches to have basically the same record and the desire to turn over most of that roster again?
The fact is we arguably had the same or deeper talent in the roster he took over. He didn't improve but failed to realize that and fired a coach to prove his point. When that backfired he still apparently resisted changing.
What's done is done. Through a combination of ignorance and arrogance, PDA dug his own grave. All that's left is for Vlade to bury him.
