One of the reasons that the NCAA added another paid coach more than likely is because there is a lot to cover in a short period of time. There are time frames within the year where coaches can and cannot instruct or practice with staff. The only time allowed with no restraints is if the player is in rehab. Unfortunetly it's like anything else in life, the more money you have to spend, the more chances of winning a championship. Being a student athlete in a top 50 program, is NOT for everyone.
It's also about $$$. Most P5 programs can afford a loaded staff. Their success depends on how many are there to help the program be successful. Even the smaller programs have more hands on deck than ever before, even in some smaller programs.
My suggestions, look at staff rosters and read bios before making a decision.
Ask questions. Understand staff expectations and goals. And understand that your player needs to find the right fit to match his goals.
