Saints running back Reggie Bush is ahead of schedule in his return from knee surgery. He is expected to be 100 percent by the start of training camp next month. "I'm not trying to go out there and rip it up," Bush said. "But I am trying to get the feel back to cutting and all that stuff." Bush participated in three of the team's five practices this past weekend. "I think he's found his niche," Saints coach Sean Payton said of Bush. "He's been really explosive for us as a returner and as a runner and a receiver; he's been a big part to us running the football. Prior to his injury last year, he was having a great year. Certainly, I think we have a good role for him, and he feels very comfortable with what we're doing."
