Bell for Diggs?

I was offered Bell for Diggs in my league. I am 5-4 here is my team. I feel like I need a running back like bell but I feel I would be taking on huge risk not knowing what he will give me when and if he comes back. What you guys think? Below is my lineup this week and on my bench I have: Baldwin, Collins, diggs, Philip Lindsey, Corey Davis, kerryon Johnson and sterling shepherd


I wouldn’t, it’s unlikely Bell plays at all this year.
