From the episode

if J.K. Dobbins goes down and then Jonah Coleman comes in and just fulfills that J.K. Dobbins role...if we're sitting here in camp and we're getting nothing but positives out of Jonah Coleman, you have to be aware of the possibility there that this may never exclusively be R.J. Harvey's backfield

STACKED’s take

NeutralRole

Coleman could fulfill Dobbins' role if injured, blocking Harvey's upside.

The source identifies Coleman as a potential threat to R.J. Harvey's workload; if Dobbins is injured and Coleman fulfills that role, Harvey's drafted three-down opportunity disappears. Coleman is ranked RB 54 in expert consensus, well below both Harvey (RB 32) and Dobbins (RB 34). The source notes that if camp reports show positives on Coleman, drafters must be aware that the backfield may never become exclusively Harvey's.
