OBJ & Mark Andrews for McCoy & Kenny G

I was just offered the OBJ side recently in my half ppr league. I’m keen but slightly concerned about RB depth.
Rest of my team
RB: D Johnson, D Freeman, D Willams, Sanders, McCoy
WR Adams, Kenny G, Kirk, M Williams, R Woods
TE Hooper
QB Dak and Matt Ryan

Appreciate any advice
