How/why is James Connor still holding up?

The man was injury riddled toast the past few years for the Steelers.

Maybe the OL is a big reason for his success but to the point where he is at the top of the scoring leaders in the league?

I know we have had our injuries this year but I find it fascinating that Connor is doing this after being DOA lately.

I have a feeling that Arizona will only go as far as Murry and Connor can take them. If they go down, the team will also.
