The fact that they'd consider him for OC when they don't have an actual HC shows how backwards they are.
Yep, I'd guess this is their weird way of buttering him up to try to get him to stay on when they hire Moore as HC.
I think all those random tidbits over the weekend like "the search may last until February", "they're interested in speaking with Glenn and maybe Johnson", so on and so forth was them setting the table for potentially waiting for Moore until after the Super Bowl.
They had to float someone like Glenn out there as well since I bet they assumed it'd be the Lions and Eagles advancing to the NFCC, and yet once he became available you haven't heard a peep.
Moore was the first interview, he's the exact kind of stooge that will let Jerry run wild with hires like Witten, and he can even be sold to the fan base based on the stats his offenses put up over the years and the Eagles success this year.
It's a no brainer, the most obvious answer is usually the right one.
