I would suggest print out the most current roster with player numbers. Obviously, with the players who have been here that isn't necessary. Although you might find some players who don't get first team reps in games may be confusing.
But for the rookies this is a must. You can't tell the players without a program, as they say.
TAKE A NOTEBOOK AND PEN!
The squads will work independently at times. Offense, Defense, Special Teams. Depending on where you sit, a small pair of binoculars might be a good idea.
There will also be players working with trainers. These are the injured guys. Usually at the ends of the field.
Your assignment:
Make a list of the injured players and what they are working on. See if you can decide if they are close to playing, or in prelim rehab. Example: Is Gallup running? Is he cutting? Does he transition to the squad work - meaning WR's when they are using the jugs or the spin and catch work.
Other than Cee Dee and Schultz, who plays what position in pass catching.
Note what the offense is focusing on. Running, passing. Who is getting work with the firsts? How is Dak's accuracy? Does the rookie look like he will beat our McGovern? How does Badass look. They say he is bigger this season.
Depending on the week you go, the further into the training camp, the closer to "real" football you might see. If that is the case, who is winning what battles?
These same questions apply to the defense. Who is playing inside on the line? WHERE IS PARSONS THE MAJOPRITY OF THE TIME? LB or Edge? Is the defense creating turnovers?
All the advice from others about water and such is good advice. I've been twice, and the last was in San Antonio. I can't comment on if they play music or have some amplified commentary or such. But the two times I went, I wished I had taken my headphones to listen to something. For some reason, unless a really good play happens, it was like a funeral it was so quiet.
Perhaps some of the people posting here could add specific players and positions for you to watch. Who they will be interested in.
Hill is one. Rumor is he is a guy to watch. What do you see? Trysten Hill #72 DT
Tyler Smith #73. He will be battling for the guard spot.
I'm certain there will be a list of people from others.
This may seem daunting, but not as much as you would think. If you get the numbers down, or have a cheat sheet, the people making plays will be obvious. But who did they beat will be important.
Good luck and take pictures.
