Should I start Lamar Miller?

I’ve got Miller but he’s questionable, I picked up Alfred Blue and I have no other RB options currently (Starting Barkley, got Lev Bell on my bench and Nyheim Hines has already played)

Should I start Miller and hope for the best or take a shot on Blue.

My 3rd option is to dabble in the waivers last minute, the options where are Frank Gore, Mike Davis and Nick Chubb but that’s about it…
