I'm not saying it isn't . I'm certainly not saying Patrick would be huge. I'm saying the odds of him being that small if he didn't have cancer is extremely small. He will probably grow more than your average rail thin 18 year old because of it.
What are you saying? That a kid who has cancer at 14 wouldn't still be showing the affects of it at 18? If so, your extremely underestimating going through something like that at that stage in your life. 14-16 is a pretty critical growing stage. Not many people go the wrong direction during those years. It's pathetic that a hatred for a coach can make someone argue against something like this. "I hate Fran so I don't believe cancer affects kids".
