This means he is forced to sign by 8/15/11 or go to school.
As soon as he was drafted he had an 8/15 deadline. Summer class enrollment has nothing to do with that. And if he doesn't sign by 8/15, he could sit on his front porch instead of going to school. I'm sure he won't, but "forced" isn't correct.
I said "forced" because of the rules according to the MLB. Bubba has entered school, which is why the deadline is in play. Had he just sat out and not enrolled anywhere, the Royals would have had his rights till next years draft. By entering into school, he is forced to sign by 8/15.
One of us is missing something. The way I read that is that the 8/15 deadline was always there, but the deadline can be moved up if he enters college full time before then. I don't think signing up for classes constitutes entering college, attending the first day does. Otherwise, with the word "OR" in there, as soon as he signed up for classes the Royals couldn't sign him. Few if any colleges have full time classes starting before 8/15, so the "entering college" deadline rarely comes into play. Maybe I'm reading it wrong, or maybe you are.
If he doesn't sign by 8/15 but doesn't enter college, he's eligible to be drafted next year, but can't sign before then. If he enters college, he's ineligible for the draft for 3 years.
Ok, yes I definitely was wrong. The deadline is there regardless of college or not, my bad.
