Vandy will lose at least half of those top 10 guys and probably more. Their 2016 class lost 6 kids. The 2015 class lost 5. The 2017 class is probably #1 because they didn't have top 50 type guys, but were able to keep all of the kids in the 100-500 range, which is quite reasonable that you are talking about 5th round money, which is where the 100th ranked kids are drafted when you add in college and international players to the draft pool.
Here is how their finance work if anyone is interested. There is a myth of "unlimited scholarships" and free rides for everyone. The tuition model at Vandy is very different from the conventional state school model. It's that way for every student, not just athletes. The sticker price is somewhere around $45k (MSU is $25k out of state), but north of 80% of students don't pay that, and most don't pay anything close to that. The Expected Family Contribution is directly tied to the family income, not a set tuition rate. For a kid from a poor family, they are basically free. A kid from a middle class family making $150k may only pay $15k. Throw in lotto money for in state kids, a half baseball scholarship, and the room and board, and you are competitive with the out of pocket cost of most other SEC schools, but it's certainly not zero. Before the change in the tuition model, Vandy had virtually no shot. State schools could always offer discounts to in-state kids that the private schools couldn't. I have a HS senior looking at MSU, so we know the tuition is around $10k in-state, and $25k out-of - state. With half a baseball scholarship, MSU could get an in-state kid paying only $5k, while a kid from Nashville would pay $22k to go to Vandy. How is that fair? The changes leveled the playing field, and have given some advantage to recruiting nationally in some instances with lower-income families, but it isn't close to what the critics want to believe when they throw around numbers like $80k.
If you want to say that the perceived "value" a kid gets when he gets a huge discount from the $60k is attractive to some, you're right, but that goes for every student at Vanderbilt and not just the baseball players. The real measuring stick for a level playing field is the out of pocket cost for each player, not the amount of aid of the scholarship package.
If it was really about the value of the scholarship, why don't they do better in football or basketball? The bottom line is that Tim Corbin is putting kids in the first round of the MLB draft every year and competing for championships. The fact that he has a highly rated school in a great city backing him and targets kids with academic mindsets who value the college experience as part of their baseball development.
