They do not line the whole team up against a fence any more.
I'm interested to see how autographs work this year. They only have 11 open practices at SJF and 5 of those are ticketed. They in the past have had 2 players per session sign in a tent after practice, but to get a guaranteed spot you basically have to get in line early and miss the practice. They don't sign for very long. And they only sign for kids.
Signing at the edges of the fields after practice is hit or miss - some players do, some don't. You never know who will be on a certain day, and where they will be so that you can get to them before they move on.
The best place that I've seen is in the walkway between the 2 stadiums, but it is reserved for VIP attendees. Looks like this:
(PS - I think the guy in the red Bills shirt with the shades is Matt, AussieW's son)
I for one am glad I'm not big on autographs...
