In-state recruiting options for 2013

Why do people ask "what are our chances" with a certain player? The only person who knows, after all, is the player.

And those players tend to give out info about who are their favorites. Hence, giving an idea of what a school's "chances" are for landing said player.
 
Jordan Knock is another 2013 recruit to look at from Gilbert. I go to school with him, and yesterday he got pulled out of class because one of the ISU assistants was there to talk with him. His dad is now the athletic director at Gilbert, but was an assistant under McCarney, so I'm assuming ISU is probably his top option. Rhoads has obviously seen him play alot, given his son plays on the same team as Jordan. He is the starting QB at Gilbert, but for ISU Im assuming he's getting recruited from a defensive standpoint for something like safety...
