Its no reflection on the WR ability otherwise it'd be Smith, all day, everyday.
Based on the QB issue though you have to go with Crayton, nice rapport with QB. He'll get you some avg/steady FPts this week.
Smith will struggle, check his stats since the QB injury. Only hope for him is Vinny getting back to full health as he has the way better arm than Carr; And if youre pinning your hopes on a 40+yr old, then you know its bad.
I'd even go so far as to suggest you consider thinking of trading him for Colston or someone, it's that bad :(
