I doubt we learn a ton from the first padded practice, no. I assume practices will be closed to media, the wild card is whether they'll do more outdoor practicing, but frankly I doubt it.
If the Hawks is like the Cook was they will have big exhaust fans that they can move tons of air through their indoor facility. Teams now are so paranoid that I doubt they practice outdoors unless they need to work on grass. I have no idea if media would be allowed to be off at the fences observing, but doubtful they can be there without an invite.
Get ready for a lot of coachspeak and retweets of coachspeek for the next month. That and trying to read WAY too far into 1.5 second clips from a supercut of practice highlights. "Aw man, 24 caught the ball, who's that? HUUUUUUGE year on the way for him, Greg!"
