Wasn't Fernandez like two years younger than Lukas V. when he ran those times.
In fact, weren't all these guys younger?
Don't think so. All the stuff you heard about Lukas being old for his grade was based on him graduating in 2012. He was technically a sophomore last year. He's stated he's graduating in 2011, thus meaning his final year will be essentially the same age as everyone else's. Webb and Ritz turned 18 in December and January of their Senior year, IIRC, making them normal. Fernandez was fairly young, as I think he turned 18 in the fall of his freshman year in college.
If Lukas stuck around for 2012, he'd be old and everyone would remember his senior year marks with an asterisk, but since he's graduating in 2011, at 18, all is well.
