Can someone explain to me why this is allowed? For example, the Flyers have 2012 draft eligible guys like Tomas Hyka invited into training camp. He was eligible to be drafted last year, but wasn't. But, I'm pretty sure he is still eligible to be drafted in 2012 isn't he? The Flyers did a similar thing with Tyler Hostetter a few years ago. Can someone explain the rule behind this or why this is?
