First saw this on Uniwatch today:  In this article on 49ers.com there are some pictures of guys practicing wearing gray facemasks, like the ones used in the glory years.  Uniwatch speculates that maybe Singletary is trying to put his own visual stamp on the team.  Could be, but I have 2 other theories...

1. Maybe they always wear gray facemasks in practice?  Anybody know?

2. Could this in some way be a preview/test run for some changes taking place next year?  There's been a lot of talk about the niners going to a new uni next season that at least invokes the 80's look.  Maybe a gray facemask is part of it.
