Meadowlark Lemon (when I was about 6-7 years old)
David Murphy (my 4-year old son got a signed baseball and a fist bump)
We're unabashed Murphy fans in our house and have been since the Rangers traded with Boston to get him.
My brother has a framed autographed picture of Payne Stewart and one of Nolan Ryan (it says, "Don't Mess with Texas" and shows him with Robin Ventura in the famous headlock, fist clinched and on its way toward Ventura). I got to display those at my house for about five years while my brother was still living at home or in apartments. He also has a Deion Sanders football that I couldn't care less about.
I was never a Jordan fan, and especially wrote him off after his Hall of Fame induction speech. He sounded so arrogant, especially compared to the humility and graciousness of David Robinson at the same event (and I'm NOT a Spurs fan, but I hold DR in high regard).
The only other player I'd like to get an autograph from is Robbie Ross. . . and luckily, there probably wouldn't be an hour-long wait for his yet (but I expect that to change soon). Still, I won't go out of my way to get it.
In general, though, I don't let other people write their names on my stuff.
But I understand why some people do.*In the interest of full disclosure, I just remembered I got Daryl Johnston's autograph in college, but I don't still have it. He was at North Texas and I saw his table as I walked to the Baptist Student Ministry. The line was about five minutes long, so I stopped by and chatted with him for a bit. He was a very nice guy. I even made him listen to me tell him that I played fullback in junior high and wore #48, but our school called it the Mooseback position. He liked that.
