I think you are being a bit unfair critiquing an 18 year olds MySpace page, Doc. Seriously, as a child of the MySpace age I can tell you that his MySpace page is very TAME and MATURE for the average high school kid. In fact I see one thing that is VERY encouraging:
Smoke/Drink: No/No
This tells me the kid has at least a decent head on his shoulders he know he needs to stay away from the cigs and the sauce (unlike, for instance, Daniel Cortes. You want to see someone with a personality disorder, go look at him!). In fact I love the fact that Walker spends his extra time doing what he loves, playing sports. He doesn't go out a drink, or party, or smoke weed, he goes to the gym and films dunk videos with his buds :)
In fact the one thing that worries me about his MySpace page is that it confirms for me that baseball is not his passion, basketball is!
Under occupation he lists... Basketball
Every photo and video is ... Of a Basketball player
Person he most wants to meet... Michael Jordan.
In fact the only baseball related thing on there is his Mood which is... Mariners ::googly eyes::
It would worry me that he doesn't have the desire to be a truly great baseball player, like it appears he has the desire to be a truly great basketball player, but that he really likes the up front money the M's are offering ;) Of course we also have a guy like Chone Figgens who is open about the fact that his first love is Basketball, but he was just too short to play.
Finally here is the proof on his MySpace page that he WILL BE Successful:
Heros... MOM
Paraphrasing... Honor thy Father and Mother so it may go well with thee, and you will have long life! :)
