We're still learning all of these new NBA salary cap rules as it comes out this week, and then I can only assume Sham will have a full awesome update and the trade machine can rule the day once again.
But there's one that immediately affects the Bulls, and only the Bulls. From Tom Ziller at the mothership:
Players with six or fewer years of service in the league can sign contracts with a maximum first-year salary equal to 25 percent of the salary cap, or roughly $14.5 million for the 2011-12 season. But if that player has already achieved two All-NBA bids, two All-Star starting nods or an MVP award, he can sign a deal that pays him 30 percent in the first year of his second contract, which is also the max for players with more than six seasons of service. This will affect young players signing their second contracts, usually following their third seasons. (This contracts go into effect after the players' fourth season.)
Those eligible for early extensions include Derrick Rose. Of those players, the only one eligible to that higher tier of starting maximum salary is Rose, hence the name. This is another form of compromise between the two sides, the players arguing that the younger players who outperform their rookie contracts were actually 'hurt' by signing an early extension, and the owners putting in such provisions to where that young player will really, really (to a Derrick Rose level) need to do well to see that difference made up.
A bit of a bummer for the Bulls, who you'd think would've immediately offered Rose the maximum they could've regardless of any such stipulation. Doug at ChicagoNow points the unfortunate-ness of the situation, especially in contrast to the Heat's star-contracts signed in the last CBA. He's right, but it could've been worse news. This does nothing to restrict what the Bulls can still do this offseason. Though in the following years it will indeed be tougher than it would've under the old agreement.
