Jefferson for expiring money, essentially. Cleveland or Portland could have had Jefferson (for Wally or for LaFrentz) last year at the deadline.
Will be interested to see the official details. Maybe a draft pick involved as well?
EDIT: Bowen and Oberto are non-guaranteed contracts, which is a huge consideration for Milwaukee. Both will likely be cut (saving $7.8 mil), thus freeing up some payroll to spend on resigning Sessions and/or Villanueva.
