There are four clear archetypes of running back the Detroit Lions want to have on their 2020 53-man roster. The do-it-all guy, who has a mix of speed and physicality necessary to make big plays running between the tackles. The agile, elusive back who can line up anywhere on the field and make men miss in short space. The speedster who can turn an inch of space into a huge gain. And the power back who can bludgeon opposing defenses like a battering ram when his number is called.
We know who will fill those first two roles.
