Here's the Arizona Rattlers football not sure who is who on here and is there any one good that sighed here.
For the first one, we're going to need some context (when, where - are these NFL players?) in order to have a chance at helping, as well as some better photos.
For the Rattlers one, I'm not sure if any players from the team have any NFL experience. Based on what I've seen, other than former head coach Danny White (Cowboys QB), it doesn't look like any of those players had significant careers beyond arena league. I think the ball if more of a curiosity for Arena league fans than anything.
