TL;DR: Lower bounds on the degree of a Chevalley group over a field of characteristic other than p have been obtained by Landazuri et al. as mentioned in this paper, who showed that for most types of groups and for most primes p it is not difficult to obtain reasonable lower bounds for the complex irreducible characters of G = G(q), using the existence of certain p-subgroups of G resembling extraspecial groups.
