There are some things about NFL training camps that you just can't know unless you're there.
If you can't be there, the next-best thing is to check out photos from those media photographers who are at camp. Presumably, that's why you're here.
By this point, you've seen all the training camp previews you can stand and now you're looking for some action.
Don't worry. The preseason is mere days away, which means the regular season is only weeks away.
While you're waiting for those, have a look at what's going on with the Lions so far in camp.
