PITTSFORD -- Here are some observations of the Buffalo Bills' fourth practice of training camp at St. John Fisher College Tuesday night:
> One day after signing with the Bills, 31-year-old running back Reggie Bush provided the highlight of the night when he took a handoff, burst through the middle and then cut to his right for a long gain. The crowd of 5,000-plus cheered wildly and broke into chants of "Reg-gie! Reg-gig!" that could be heard at the end of the two-hour session as well.
"I had to remind some people that I've still got it," Bush said afterwards. "I'm 11 years in, but I'm not done yet. So I let 'em know I've still got the wheels."
The play made up for Bush's drop on his first attempt to field a punt launched from a Jugs machine. Punt returning is the primary role he is expected to fill. But Bush also wanted to prove that he can make a significant contribution as a running back. When fans saw his wheels, they probably didn't feel quite as upset about the fact he was wearing jersey No. 22, which had belonged to one of the Bills' all-time popular players, Fred Jackson.
"I felt very familiar," Bush said. "I felt right at home. It felt natural and felt like I didn't have to really do anything extra to make those moves. Hopefully I can continue just to progress every day."
> Word is that wide receiver Sammy Watkins will practice on Monday, Aug. 8. That will mark his first time on the field since undergoing foot surgery in the offseason.
> Best defensive play of the night I: linebacker Lorenzo Alexander came screaming into the backfield unblocked to tackle James Wilder Jr., before the running back could take a step. The crowd loved it almost as much as Bush's run.
> Safety Aaron Williams made a nice breakup of a pass over the middle to tight end Blake Annen. Williams has looked exceptionally quick and athletic through the first four practices.
> Best Defensive Play of the Night II: Safety Jonathan Meeks snatched a deep throw from rookie quarterback Cardale Jones and returned it for a touchdown.
> Another practice, another strong showing by cornerback Stephon Gilmore. Ronald Darby, who had struggled through the previous two sessions, had by far his best practice to date. Both players were doing a good job of contesting plays. On the flip side, there wasn't a whole lot of challenging being done by many of the receivers other than Robert Woods, Greg Salas, and Dezmin Lewis.
> IK Enemkpali is abysmal in pass coverage. He has struggled with it from the beginning of camp. And on Tuesday night, Greg Little simply abused him on a play in a seven-on-seven passing drill. To be an outside linebacker in the Bills' defense, you don't just rush the passer. You have to cover, and that is a serious flaw in Enemkpali's game.
> Through all of the Bush mania, Jonathan Williams was able to remind people that the Bills still have some good, young depth at running back with an impressive run. Williams shows good body lean and vision. For a rookie, he seems to consistently hit the right hole and is patient with his blocks.
> One of the more entertaining moments of the night was when fans began jeering tackle Jordan Mills for insisting he had drawn rookie Adolphus Washington offside but was, instead, flagged for a false start. The jeers got louder as he was forced to take a "penalty lap" on the track surrounding the field.
> Team owners Terry and Kim Pegula attended their first practice of training camp. Terry watched much of sitting in a golf cart with General Manager Doug Whaley.
