I've been to a couple autograph signings for Sherman. I took my nephew who was in awe of him to his SI signing at Lucky Strike. Nephew was so nervous but Richard was so gracious and intense that you kinda get the feeling right away that he's a pretty good dude. He really puts himself out there. Before the signing there were hundreds of people in line and he walked down the whole line shaking hands. No doubt in my mind that he's a guy who is going to do some really good things outside of football. he's already been involved in tons of charities and events to raise money for people who need it. That's why I couldn't care less about what he does to get attention - he's basically realized that as a non-first round pick, he can play well and EVENTUALLY get recognized - but he can do so much more good for himself, his family, and the organizations he cares about by getting his name out there.
Both times I met him it was in long autograph lines, but he took the time to engage with everyone. At the SI signing he was picking people up and holding them while they were getting pictures taken and always seems happy to be there. At training camp he was one of the guys I saw staying as long as he could to sign things and seemed reluctant to come off the field when the staff was calling for it.
