The rhetoric agents use to lure kids into these decisions focuses on the "now" without mention of the future. The general case (as I understand) is presented like: "in a month you'll be a millionaire and playing the sport you love." Agents have professional, slick presentations that come off as "cool" and "mature/serious" - intended to make the colleges these kids are considering to leave seem hokey and bush-league. Not saying SU is hokey, but this is the way many agents drive the perception-wedge between college and pro and entice kids to make decisions that may not be ideal.
Of course it's in every agents' best interest to sign players today.
