I am not a big Jordan fan off the court, but I don't think that letter was so bad...it might not be grammatically perfect, but its written to a girl...unless she's a Rhodes scholar, she doesn't care about all that either. It's hand written and signed by him, the boy was in love, or in heat, or both...
He is known by friend and foe alike to be a very intelligent man, he knows a lot about topics other athletes don't know about. I have heard beat writers speak of how "well-rounded" he was as a person overall, and how extensive his knowledge was in his youth and is now.
I would hate to have some of my old love letters, filled with fragmented sentences and misspelled words for everyone to see...lol
