Via Brian Schmitz of the Orlando Sentinel:

The Magic franchise record for consecutive victories is nine, set twice, in 1994 and in 2001.

A victory against the Wizards would match the second-longest winning streak in Magic history, when the 2005-06 team won eight in a row.

"We're just trying to get better — no matter who we play at this point," center Dwight Howard said. "We just want to continue to do the things that are going to make us a lot better going into the playoffs. "Our goal is to win a championship."[...]

"There's not much joking around," point guard Jameer Nelson said. "It's a lot more serious and especially now. Everybody is focusing in on everything."
