I'd imagine people wanting you to sign things all the time and asking the same dumb questions over and over would get old. Not to mention those asshats who just want stuff signed to sell it off.
They made it clear that fans were not to ask anyone for autographs, and I was perfectly fine with that as they wanted to keep things moving and give everyone a chance to say hi. I just appreciate the (mostly) lesser-paid players actually chatting with the fans and shaking hands. They truly seemed to appreciate everyone coming out.
