Each stage of Derrick Rose’s rehabilitation from an ACL tear in his left knee has been documented in great detail, with, at one point, the ability to jump off his left leg rating as a major priority in the progress toward a possible return. And, if we believe there is a chance he will return this season, video circulating from Rose’s most recent pregame workout serves as encouragement. Before the Bulls’ 99-85 loss to the Pistons, Rose took off toward the rim and dunked off his left leg without a hitch (via Yahoo!Sports Ball Don't Lie). Rose has remained open to playing down the stretch for the Bulls, but is just as close to calling it a season and returning anew in 2013-14. While this most recent video doesn’t mean he’s headed toward one or the other, it’s an obvious sign he’s taken serious steps toward full health. Before this, there were stories of Rose taking stand-still jumpers, then moving and the cutting on the left knee and, finally, partaking in scrimmages for the first time in February. Most prominent here is the fact that Rose’s trajectory has moved on a steady line. When exactly that will lead toward the Chicago Bulls' lineup is yet to be seen.
