I am from Missouri, and I've watched C.J. Jones (ran 1:49 in HS) and this gentlemen at a few meets.
By all accounts, they are nice guys and work hard. Having said that, they will be subject to criticism because of two factors:
1: They are both early maturers. They simply got more of the testosterone burst from puberty early in their running career compared to many athletes. Those of us who coach have all had athletes like this.
2.: They ran age group track extensively before their high school careers. This means they are (or were, in the case of CJ) already farther along on their improvement curve than many athletes just taking up the sport.
With athletes like Brandon and CJ, you just won't see freakish time drops from freshman to senior year like you do with kids who either take up the sport as 14 year olds or hit puberty fully at 16.
Trust me, Brandon is aged correctly. He's a nice, fast, hardworking kid who has already run track and hit a good chunk of his physical maturity.
