"Suggested" is absolutely correct. College players are ADULTS - not 12 year olds. Accordingly, college coaches do not have "hand holding" and "babysitting" in their job description.
If a kid comes home and sits on the sofa, pigs out on Twinkies and potato chips, and does nothing to stay in shape, most likely she will pay the price when she returns to school. Fortunately, it's a rare college player who would do that, because it was their discipline and work ethic that got them to the college level in the first place. They KNOW what's on the line, and they know that THEY are the ones in control of their destiny by the choices they make.
I guarantee you every single college kid knows exactly what they SHOULD be doing over their breaks. With a lot of scholarship money on the line, college coaches tend to be a little bit controlling - as they SHOULD be, or they won't be in their coaching position for very long.
