From the ESPN article, it appears that $5k is the minimum:
In a partial victory for the NCAA, though, Wilken said it could set a cap on the money paid to athletes for use of their names and images, as long as it allows for no less than $5,000 per athlete per year of competition for players at big football and basketball schools. Individual schools could offer less money, she said, but only if they don't unlawfully conspire among themselves to set those amounts.
Seems like the bigger schools that can offer more marketing opportunities will land the highest rated players.
Would you pick KY or MU if you could get way more $$$$$$ by signing with KY.
