I'll never understand high school pitchers pricing themselves out of the first round just so they can go to college. There are a lot of bad things that can happen to your arm over three years before you're eligible again.
Maybe the college experience is worth $2.5 million to him, but boy that's just risky. It just seems like taking the money and doing college later is just an infinitely smarter move.
Vandy provides a pretty decent education and they have a reputation for not abusing their pitchers. It would be one of the few colleges I could see a pitcher skipping pro ball to go to school.
