My guess is that the total meets the League requirement of veterans dressed for each preseason game. I think the minimum number is eight. I don't see one next to Adam Hall, however, but he would be the 8th/9th with Streit.
This is my guess as well but the fact that Streit and Hall don't have dots kinda threw me for a loop.
I know it's only preseason but I can't wait to see this game, I don't know why really.
