He likely was attractive to the 49ers - and vice versa - because the Tigers run a zone-blocking scheme that's similar to San Francisco's and which highlighted Schrader's decisive running style.
Brugler rated him as a fifth-sixth round back and Schrader was his 14th highest-rated runner, two spots behind 49ers' fourth-round draft pick Isaac Guerendo.
