EAST RUTHERFORD, N.J. -- No one has watched the New York Giants' offense more than first-round draft pick Odell Beckham Jr., who's been watching practice from the sidelines since pulling his hamstring on the first day of camp. And what Beckham has seen so far has him extremely optimistic.

"It has potential to be, if not the best, one of the best in the league," Beckham said before Giants practice Tuesday. "When you have a receiving corps like we do and a great quarterback along with the backfield and the tight ends and much improvement from the offensive line, I don't see anything but being one of the best in the league."

Beckham is a rookie who wasn't in the league last year, when the Giants finished 28th in total offense. And he hadn't been drafted yet when they changed offensive coordinators and signed new starters at left guard, center and running back. And it's not as though he's been to other camps, where teams have tight ends with a little bit more experience as productive players in the league than guys like Larry Donnell and Daniel Fells have. So it's possible that his perspective is a bit skewed. But it's training camp, and it's time for optimism.

Offensive coordinator Ben McAdoo, who's still installing concepts and teaching them to all of the new personnel, is a bit more mellow in his assessment of where things stand.

"Monday night [Sept. 8] in Detroit, we need to be 100 percent ready to go," McAdoo said. "We're not there yet. We're making small strides. You'd like to say you can take two steps forward every day and one step back. We took a couple of steps forward last night. In practice, we had a good day out there. We just need to keep making small strides."
