There was another Matt back in the 2000s who won the 100 and 200 in California, year 2003. I believe his name was Matthew Bruno and he ran against Reggie bush, and Alyson Felix also competed in the state meet that year. Bruno was one swole kid. Rumors had it he was on the juice, but it could also be due to the fact the black kids were angry and jealous a white boy was dusting them on the track. And as you said about hs stars fading in college, Bruno never surpassed his high school best marks at UCLA.
