Khalifa (who got allegedly $600K for 2 years), Hall and Saunders were all top 35 players in his rankings. Khalifa is still ranked 18th and Hall and Saunders are out of the rankings since they returned to BYU.
So again, on what planet is Robinson worth over $1M? Just being really desperate or really stupid isn't a good excuse to pay several times the market rate for an 86th ranked portal prospect.
Especially when you just lured back two players better than him for less money.
