I was critical of a signing-day spectacle where a kid revealed one school's shirt, only to take it off to reveal another school's shirt, only to take it off to reveal his REAL choice's shirt. I thought that was pretty inconsiderate to those first 2 schools. The player involved in that spectacle could very well be a great kid, but I think that was a poor choice, and I question how the adults in his life could let him go that route.
Perhaps it is hypocritical, but I don't feel the same way about this video. For one, there was no "fake reveal" involved. But it also does not smack of self-obsession so much as a desire to be creative and to control the narrative of one's life (that is my interpretation, anyway). I also admire the effort that went into it, and I feel sincerity comes through in the final product.
A simple phone call to the coaches would have sufficed, but this seems like it was fun for the athlete, his friends, and his family, so have at it.
