Selecting three players at the same position is a trend that began during the 2017 draft and is something that at the time flew a bit under the radar.

The 2017 NFL Draft was Ted Thompson's final as General Manager, and he would select three running backs that year--Jamaal Williams in Round 4, Aaron Jones in Round 5, and Devante Mays in Round 7. The following year during Brian Gutekunst's first draft as GM, he would take three wide receivers--J'Mon Moore in Round 4, Marquez Valdes-Scantling in Round 5, and Equanimeous St.
