Few things.
1. There is absolutely NOTHING wrong with out front court. Our front court will likely be better than Atlanta's with Millsap next year, and they are all 24 or under (minus, Booker I believe.) We have the financial capability to keep them together for a while because even though we are starting to bump against the salary cap, the luxury tax is a long time away. People complaining about our front line situation are daft. Our backcourt needs work, however. Was Paul Millsap going to play shooting guard?
2. No one knows what was on the table for Millsap or Big Al. I got the feeling that trades could have been made but they required us taking back multi-year contracts or packaging some of our young talent. We weren't going to do that. That was the right decision as we got the draft picks and the expirings we wanted in the offseason with our cap room. Jazz have played the finical aspect of the rebuild like a Stradivarius, even though some of it may appear to be luck (like Hayward earning his contract.)
3. The Jazz have made some stupendously good moves, like trading Deron and purchasing the pick for Gobert. They also have a passel full of picks that can be used as assets, as adding even MORE young talent at this point may not be what we need to do.
4. If you go back in time and change one thing, not everything else but that thing pans out the same. We wouldn't have our current team + Milsap, for instance. It is likely we never purchase the pick for an extra big man at that point so the freakin' Lakers get Gobert. So you got two good PF's and Kanter trying to hold down the center position. You could have moved Millsap to SF, but then we likely don't match Hayward. Sometimes people complain just to complain. There is nothing wrong with our current situation.
