Just what will Brewer really be worth?

The Jazz on Monday picked up the $2.7 million, fourth-year 2009-10 season option on the rookie contract of starting shooting guard Ronnie Brewer, a late lottery pick in 2006.
That means Brewer will be eligible next offseason for a multi-year contract extension, a la Deron Williams this past summer.
So just what is a young, athletic starter who averaged 27.5 minutes, 12 points and 1.7 steals per game in his second NBA season worth?
Kyle Korver money, which means somewhere between $4 million and $5 million per season?
Korver, it should be noted, finished last season as Brewer’s backup — but frequently closed games instead of him.
Matt Harpring money, meaning about $6 million per year?
Harpring, it should be noted, is a veteran backup prone to illness and injury — something Brewer, generally speaking, is not.
Mehmet Okur money, meaning about $8.5 million per season?
Okur, it should be noted, has appeared in one NBA All-Star team and has one NBA title ring won as a reserve.
Williams max money, meaning enough to buy a really cool new Maserati (which the Jazz point already has) and all the golf courses in Utah?
Just what, really, will Brewer be worth?
You make the call.
