I thought that was kind of a silly piece, in the sense that there's no accepted metric for how secret a team is, but with that said Oregon has definitely locked things down this year.
The first couple of years under CK were completely open, with the exception of some bowl prep and civil war week (which follows a longstanding tradition.) But since LSU gameweek practice has been closed, and it appears that's going to be the way things go from here on out.
Honestly I'm surprised more programs haven't converted to that mode of operating sooner.. the internet makes it really difficult to surprise anybody with new wrinkles and schematic ploys.
I think it's funny, btw, that Goe doesn't spend any time discussing the ways Oregon (and not just the AD) stonewalls public records requests and seems to have a, to put it mildly, deficient office for dealing with those inquiries.
