I remember a time when a pretty good QB name Eric Crouch came close to leaving NU. At that time many fans like many on this board said let him go who needs a quitter. Fortunately the coaches were a little more tolerant. They massaged his ego a little and he stuck.
Part of being a competitive player is to have a lot of confidence in yourself. Many of them also have huge egos. You don't get to be a top 50 recruit or the number one JC player without a lot of talent. I agree that these players had yet to raise eyebrows at NU. However, anyone who is paying attentions will notice that few players on this team are.
We should all remember that these kids are playing in a new offense. They are not sure of their assignments, they don't know what to expect from their teammates, the line is not great, they have not established a link with the QB. It is not hard to see where a kid might feel lost.
While it is easy to sit on your couch and say these guys just need to shut up and suck it up, you need to remember the program needs players with this type of talent. Both of these players have the potential to be game changers and NU has been woefully short of game changers lately. I am sad to see them leave.
