Was just browsing around and found a little news on practice that I didn't think had been posted here:
Philly Brown, Devin Smith, and Evan Spencer seem to be taking the most first team reps at WR with Fields, Tyrone Williams, and Michael Thomas seeing 2nd team reps.
Jacoby Boren has moved into the 2 spot at center, passing Bobek. Also Decker as been playing a lot of RT for the second team and even got a few first team reps.
Sorry if this was already posted somewhere! Just thought I'd share a few things I had found.
