The Bulls are assured of home court advantage through the Eastern Conference playoffs with the top seeding.

"Today, we are the number one seed. That feels pretty good."
Carlos Boozer, a free agent acquisition in the off-season, had 24 points and 11 rebounds Friday, while point guard Derrick Rose had a quiet game with 11 points and eight assists but remains the favorite to capture the league's MVP Award.
