I am confident that Frost and the coaching staff is focused on the team. However, these players put in way too much work during their youth and high school days, only to come to college and sit on the bench for 5 years. They want to go to college and play. That's what is leading to the proliferation of transfers, especially at the QB level. If the grad transfer rule were available 25-30 years ago, I would think guys like Berringer, Turman, Gdowski, and others would have left NU to start at another school. That doesn't make them less of a teammate or someone who doesn't like the college experience.
One final note. If you don't think that playing Division 1 sports isn't basically a job, you are wrong. These men and women are putting in 20 hours of week in official practices/meetings, another 5-10 hours a week in training, another 5-10 hours a week in personal player development, along with the number of hours studying and being around the facility. These college athletes aren't like normal students.
