  The Chow class of the closure of the torus orbit of a point in a Grassmannian
only depends on the matroid associated to the point. The Chow class can be
extended to a matroid invariant of arbitrary matroids. We call the coefficients
appearing in the expansion of the Chow class in the Schubert basis the Schubert
coefficients of the matroid. These Schubert coefficients are conjectured by
Berget and Fink to be non-negative. We compute the Schubert coefficients for
all sparse paving matroids, and confirm their non-negativity.
