Pittman or Carson?

Standard (non-ppr) league. Should I start Chris Carson or Michael Pittman in my flex? Carson has tough Steelers defense, coming off neck injury, and unsure how he will be used with Collins in light of injury. But he’s still a starting RB on an offense without it’s starting qb so they should lean on him. I’m leaning Carson. Thoughts?

Do we know the status of Carson for sure yet? He didn’t practice yesterday and if doesn’t again today I would be very concerned about playing him. I think I’d start Pittman if Carson doesn’t practice today, even if he is a “good to go” on sunday.
