Robert Turbin appears as quick and fast as ever after having surgery on both hips. It had been reported earlier that Turbin had offseason surgery on a hip, which caused him to miss OTAs and minicamp. On Wednesday the team revealed that Turbin had surgery on both hips. The results seem pretty dramatic, as Turbin almost daily is earning raves. “Interesting to see Turbin come back,’’ Carroll said Wednesday. “He had double-hip surgery, and you don’t know what you’re doing to get. He looked the best he’s looked — very quick, explosive, so he’s really made a good first impression. Had a big day a couple of days ago.” Turbin is competing with Michael and Thomas Rawls for a backup spot behind Marshawn Lynch and to show the team he can be an heir apparent, if needed, at some point over the next few years.
