Not a fan of this deal, AJ Green is playing behind the 3rd best pass blocking line and he's Dalton's fav target... yikes. Advanced accuracy % is showing Dalton as 4th best in the league as well. To your credit, Green is registering as league average on receiving but he's an elite WR, he's going to rise sooner than later. In your defense, Cobb/Fitz/Moncrief are hitting right now (but we don't know if Moncrief will continue to hit when T.Y. is back).
Arian when healthy is obviously better than JStew, but in the meantime you are left with Doug Martin running behind the worst run blocking line in the league. I'd actually rather have Matt Jones in there because he can churn out yards on his own better than Martin, both lines suck. Overall, you aren't hurting yourself THAT much because JStew gets vultured by Cam/Tolbert in the red zone and he's capped at a ceiling around 8 points a game without TDs, plus he's frail (hurt knee this week, surprise). He's also pulling a -1.8 in rushing this year.
In the end, I think it was a risky, ballsy deal because I'd rather have stronger WR than RB depth due to risk exposure and the fact it may take Foster a few weeks (if ever) to regain form. He's not rushing behind a world class Oline anymore, in fact they rank in the bottom third right with Carolina. Yeah they were top 6 last year, but they aren't looking like a top 10 run blocking team after two games. Small sample size I know.
Losing some regular season games is perfectly acceptable. I'm hoping to peak towards the end of the season (fantasy playoffs and championship) unless foster goes down with another injury. My plan is to stream Smith/Fitz/Moncreif/Bryant (once he comes back from suspension) into WR2 and the leftovers with Jones/Martin into my flex.
I actually did start Jones tonight instead of Martin.
