Well, honestly. I'd like to see them trade Z-Bo later in the year, probably to a team who will have 4 go down. Like Minnesota missing KG, Houston who needs a credible starting PF (Howard doesn't cut it for me) to try and win the title. NY would probably take Z-Bo as I don't really think Isaah is sold on Lee or Rose.
There are plenty of places Z-Bo could go. Miles is a different story. Nobody will take him so he either needs to Shawn Kemp his way out of town or get waived and pray that somebody picks him up so you can get that contract off the books.
Zach is a good starting PF. I'd put him as top 5 in the West behind KG, Marion, Duncan and Nowitzki but thats just me.
He can score, rebound and his defense is steadily improving.
The 4th quarter thing is something thats comes from having a young team. They rarely fell apart when they had Steve Smith, Bonzi, Rasheed, Damon, Sabonis, Pippen because they had veteren leadership, an outside threat, and a couple guys who can change the momentum in a snap.
