Smith is probably the biggest enigma on the team. I'd bet even some of his teammates aren't sure what to make of him sometimes.
Probably because when you an a$$ to so many people in real life, not everyone is going to love you no matter how many TD's you score on Sunday.
He can be a complete jerk, and often is, but he also occasionally can seem like the nicest guy around. This past year, out of the blue and with no prompting, he walked over to a friend of mine and his kids who were standing at the fence after a training camp session and signed an autograph for them. Not too many guys were signing that day, and Smith hardly ever signs, but this day he did.
Is he likely kind of a jerk overall? Possible (some would say probable) but there are times when he'll surprise you.
