If I'm okay with having an academic scholarship stripped away because they couldn't keep up with the measurables, then why can't I be okay with an atheltic scholarship being stripped away for the same reason? In theory, I'm with you. However, I'm more concerned with the judgment call related to the sports side of things. It's easier to be fair on deciding who retains scholarships and who doesn't on the academics side because of the objectivity involved with the GPA scale. Athletes aren't afforded that measuring stick - which is where I start to have issues.
Maybe somebody better versed on how the scholarship contracts are drawn up can chime in to add some input? But the way I see it, a University should have to honor their committment to the student-athlete on any athletic scholarship so long as the student-athlete is going to practice, meetings, workouts, etc. I'd probably be okay with yanking a scholarship if adequate effort wasn't present (i.e. athlete shows up, but doesn't push themself) - that's about the only gray area I'd be comfortable with. An athletic scholarship should be a bilateral agreement between the student and institution where the student says something to the effect of "I accept scholarship and I promise to attend every practice, workout, meeting, and game" and the institution says "I promise to fund your education if you attend every practice, workout, meeting, and game". I think if the student-athlete holds their end of the bargain, they University should as well.
Again, if the athlete is merely showing up, going through the motions, and not pushing themselves to their limits, they should be fair game for losing their scholarship. Defintely not objective, but a much better reason than cutting a kid loose because he didn't turn out to be the superstar you had envisioned. Plus, there's always the chance that an athlete isn't producing on the field due to the COACHING STAFF failing at their own jobs (i.e. providing inadequate training, playing the kid out of position, etc.) I think that's an often overlooked factor in this argument also. What happens if you recruit a LB, offer a scholarship, decide you have plenty of depth, convert him to a DE, and they just suck at transitioning to that position? Cut him because you 17ed up?
