In the first half of Thursday night’s 97-87 loss to the Nuggets at the Pepsi Center, Bulls point guard Derrick Rose looked like he had started to turn the corner. Not just in the literal sense — though he did that, too — but in terms of making meaningful progress in fighting through his early-season offensive woes. Rose shot 7-for-12 from the floor for 15 first-half points while matched up with Denver’s Ty Lawson, one of the league’s up-and-coming point guards. Now, in the second half, things fell apart for both Rose and the Bulls, as they scored 14 third-quarter points, then got blitzed by a 13-0 Denver run that pretty much ended the contest. Still, in Rose’s 33 minutes, he finished with 19 points on 9-for-20 shooting before Bulls head coach Tom Thibodeau wisely sat him for the remainder of the evening midway through the final period.
