I really don't understand how a guy like that can jump around so much at the high school level. Do these states not have a residency rule? I'm pretty sure in Ohio you have to live with a relative in the school district in order to transfer to a particular school. Unless these were all private schools. Seems like a huge waste of time and money traveling back and forth.
Where I live all of the districts have open enrollment. Meaning, if you can provide your own transportation, you can attend that school. In the beginning, the school districts had to border one another, not sure that is the case now. However, if you switch schools (with the exception being going back to your home school) you have to sit out a calendar year from sports.
