The personal finance decisions for a 21 YO star athlete are not simple.
First, it would be smart to delete his "wants" from the decision tree and concentrate on his "needs."

Second, there is the valuation issue, which turns on net rather than gross numbers. For example, income in Texas is worth much more than in states with significant income taxation. Cost of living in metro NYC or LA or SF or DC is a six figure differential over having room and board provided in Austin. Offsetting endorsement deals in LA or NYC might be unlikely for most.

Third, there are longer term considerations. Residual benefits of a degree now vs. a degree later, or no degree at all, are measurable to an analyst and of greater or lesser meaning to a future pro depending on his long term name value; e.g., KD and VY have extraordinary long term name value that makes a degree have virtually no long term income value in comparison.
Weigh the depth of the current draft and one a year later against the likelihood of reaching a lucrative second contract a year earlier.
I think the chance of a career ending injury would not be weighed because it may have the same long term effect whether sustained under a lucrative NIL deal or under a first year professional contract - but insurance issues and CBA health care provisions may make weighing injury potential another variable.

Two and three are tricky issues for most, but standard fare for a financial advisor.
The first issue is the most pressing: does the player NEED the most dollars today? Is his family comfortable or living paycheck to paycheck? If the current need is there the third issue, long term consequences, falls out of the matrix. Only net current value need be considered.
