Their status for Week 3 is up in the air but it will be a tough matchup at the Vikings. If Jacobs can't go, Richard and
Washington would see an increase in work at RB. If Williams can't go, Renfrow probably becomes the WR1 with guys like Grant, Harris and Nelson having to be the next men up. TE Darren Waller would probably see more work as well if Williams can't go.
This is a good sign for Jacobs who should see the biggest workload. HC John Gruden has been on record as saying he expects Jacobs to be the NFL Rookie of the Year, so he's expected to put up fantasy numbers as a result. The story expects Richard and Washington to stick around behind Jacobs.
Martin mysteriously exited after a pretty productive first half against the Cards, we only later found out it was an ankle issue. It looks like the team wants to give Washington some carries, perhaps even if Martin is OK, which would potentially turn this into a three-headed backfield.
