If KOC going 4-4 on getting superstars in the draft with Hayward, Burks, Favors and Kanter, then we are in a great position to pick the to keep the best ones as they would be restricted free agents. Or we can trade one away for future draft picks and the cycle begins again. Or you keep the ones that want to stay in Utah the trade the others. The Jazz would have the leverage. Or you just pay the luxury tax and win multiple championships. This is a good thing.
The Lockout ensured that their are powerful reasons (millions of dollars) to stay with the team that drafted you (or the team you get traded to on a rookie contract.)
It is far more likely that only 1 or 2 of them will become stars. The others will probably just become good NBA players.
You are worrying about things that you don't need too.
