I've seen some Tweets from Marcus Fuller (Strib) commenting on how the team looks more athletic and has a lot more size (or length...)
for these type of workouts, you really can't tell much more than that.
as a guy who has sat through more practices than I can count, I think I can say that most practices are pretty freakin' boring unless you are the most hard-core fan of all time.
I covered an NFL training camp for 4 years, and most of the time, the media members were sitting on the sideline complaining about how boring training camp is.
