Waiver Pick

My team is 0-3, I have first waiver priority and I need a win now. It is standard 6 pt league with heavy bonuses for long scores. You can only roster 5 Rbs and 4 Wrs or vice versa. Here my roster

Josh Allen
Baker Mayfield

Dalvin Cook
Leonard Fournette
Kerryon Johnson
Tevin Coleman

DeAndre Hopkins
Chris Godwin
John Brown
Golden Tate

IR - DeSean Jackson
IR - Tyreek Hill

I need a win this week but not sure who I should pick up with the first pick. Options are

Wayne Gallman
Drop Mayfield and grab Daniel Jones
Sterling Shepard
Phillip Dorsett

Thoughts? I have an open spot on my roster for an RB or WR due to the guys on my IR.

I lean toward Gallman, but how many of each position do you start?

2 RB 2 WR 1 Flex
