Henry, Woodhead, Gore, or Martin (STANDARD)

I’m in a real tight spot here, with RB being one of my biggest weaknesses all season. Playoffs on the line, I most likely need to win this week to make it. For my RB2 slot in a STANDARD league, should I pick:

Derrick Henry (@ IND)

Frank Gore (vs. TEN)

Danny Woodhead (vs. HOU)

Doug Martin (@ ATL)

ps I have D. Murray in my RB1 slot
