Update: Akis from Sactown Royalty has a terrific FanPost on why Brockman was such a favorite among Kings' fans.
Yahoo's Adrian Wojnarowski reports that the Bucks and Kings have agreed to a sign-and-trade which will send second year power forward Jon Brockman to Milwaukee for the non-guaranteed contract of Darnell Jackson and future second round pick. We've assumed for some time that Jackson was a goner, but it remained unclear if the Bucks would try to add another big body to replace him or simply go with the significant collection of PFs already on the roster. No terms have been mentioned, but by acquiring him through a S&T the Bucks would not have to use their bi-annual exception to give him more than a minimum-level deal [update: A Royal Pain says he'll earn around $1.5 million per over an indeterminate number of seasons].
I won't pretend to know too much about Brockman's game, but he does seem much more useful than Jackson. Despite standing "just" 6'7", the 255-pound Brockman is a tremendous rebounder and hustle player, qualities which seem to have endeared him to the Sacramento faithful. Never a bad sign. He had the highest offensive rebound rate in the league among players who played more than 20 games last year, which helps explain his healthy 53.4% shooting from the field. The Kings likely didn't see much of a role for Brockman with young big men DeMarcus Cousins, Jason Thompson and Hassan Whiteside all under contract, but then again you could make a similar case for the Bucks.
With Drew Gooden, Larry Sanders and Tiny Gallon already joining Ersan Ilyasova and Luc Mbah a Moute as power forward options for Scott Skiles, you can only wonder how long it will be before the Bucks make a move to deal one of them. Incumbents Ilyasova and Mbah a Moute would be the obvious trade bait, particularly given Sanders' fine showing in Vegas and Skiles' recent comment that he'd be "shocked" if Gooden isn't the opening night starter. Still, Brockman doesn't really replace any of the Bucks' existing pieces at the 4--it's like the Bucks are trying to acquire every flavor of the power forward rainbow. They all do different things, which should make Scott Skiles giggle with delight (you know, if he was actually capable of giggling).
Presuming Gallon and 37th overall pick Darington Hobson are also signed, the Brockman addition would put the Bucks at 14 roster spots, with the final slot reserved for a backup to Brandon Jennings [Update: problem solved]. Gery Woelfel writes that the Bucks continue to discuss a broad array of backup PG options, including Earl Watson, Luther Head, Travis Diener, and (wait for it...) Ramon Sessions.
