So defensive right off the bat..lol You are naive if you think scholarships are not renewed due to injuries or performance. Is that the official cause - NO....All a coach has to do is tell a player they aren't starting or they won't play a big role next year. Most players who want to go pro are likely to transfer..Sure some will stay in that scenario. Whether its annually or guaranteed coaches don't like to pull scholarships period but there are other ways. There's a lot of grey area ...Below is the real world
The following reasons have different rules for schools that follow Power 5 rules and for the ones that don’t, so make sure to read it until the end:
5) Athlete Violates Non-Athletic Documented Policy
If your school follows this Power 5 rule, it means that they might take your scholarship away if you fail to comply with some academic standards or some other rules specified by the athletic department or by the team.
6) Injury
This is where it starts getting a little complicated. If you were awarded a scholarship for an established period of time, the NCAA states that a coach cannot reduce the scholarship during that time due to “an injury, illness, or physical or mental medical condition” of an athlete.” For schools that don’t follow Power 5 rules, a coach might decide to not renew an injured athlete’s scholarship once the initial scholarship period is over.
For schools that DO follow Power 5 rules, a coach cannot take that into consideration when debating whether to renew the scholarship or not. So if you go to such a school, get a scholarship for a year and get injured during that year, a coach technically cannot take that into consideration when deciding if he’s gonna renew your scholarship for the next year or not. However, in reality, things do not always happen that way and sometimes coaches might find a way to get that scholarship taken away from you.
7) Not Performing Well
This has the same applications as the injury rule: a coach cannot cancel your scholarship during an established scholarship period due to “ a student-athlete’s athletic ability, performance or contribution to a team’s success.” Power 5 rules establish that a coach cannot consider that when it comes time to decide to renew a scholarship or not. So if you get a one-year athletic scholarship, work extremely hard, but still are not able to make the starting team, a coach from a Power 5 school cannot technically reduce or cancel your scholarship because of that. Once again, some coaches might be able to find a loophole and still take your money away from you.
8) New Coach – FOR ALL SCHOOLS
At the end of the day, a coach is the one responsible to make the final decision of how much (and if) an athlete will receive a scholarship. What happens sometimes is that Coach X will bring you in and promise you a certain amount of money for each year. Then, for some reason, that Coach is fired or resigns and Coach Y is hired. Coach Y might not see the same potential in you, not like your attitude, or just flat out be an a-hole. If he’s really committed to getting your scholarship taken away from you, he might be able to find a reason to do so.
