In academia, there's a known mark that is agreed on and known by both parties before hand. While the student has to make certain grades and other criteria to still qualify for his scholarship, and the scholarship will be pulled if he doesn't reach those objectives, the academic student and his family aren't fed misinformation in order for him to attend school there. He doesn't have advisors telling him how his professors need him and how they'll sculpt him into a successful student. The advisors don't make subjective decisions on the academic student's scholarship either.
The two are very different, and the way you are comparing them, the student on an academic scholarship's standard of making a certain grade is equal to a student on an athletic scholarship seeing playing time. One is in the student's control and the other is out of it. In actuality, the equal comparison to a starting athlete would be a student making a dean's list or some sort of accomplishment like that. That way they match up to their peers equally. A starting athlete or key contributor is seen as one of the top players on the team, due to the amount of playing time he's given. So a student must be seen as one of the top students in the entire school for the comparison to be valid.
Likewise, for the comparison for the academic guy to lose his scholarship due to poor grades, absences, etc., the athlete would have to violate his eligibility, whether because he didn't make the grades, violated an NCAA rule, or if he broke a team rule. An injury would not fall under any of those, since that's like an academic guy having an excused whatever.
In the end, if an academic student is making his grades, attending all his classes, and putting in the other work to sustain his scholarship, then he should keep his scholarship. If an athletic student is putting out his maximum effort, is attending all the practices/workouts/activities, and is putting in the other work that is required of him/keeping out of trouble, then he should not have his scholarship pulled either. A guy should never have his scholly revoked solely because he's 3rd on the depth chart and the coaches want to make room for their recruiting class, and doing so is indefensible, in my view.
And yes, if Dooley resorts to oversigning, I will think less of him and will criticize him. This is a black mark on teams, and if every team in the nation oversigned and then just trimmed the fat before the season like the pro teams are required to do, then the gap between the SEC and other conferences wouldn't be big at all. Until the SEC cracks down on this, I can't in good faith brag about SEC dominance knowing practically the entire SEC West oversigns.
