neither Dobbins nor Micah Johnson are far behind IMO. this injury might be enough for either to take over for good.
That is the beauty of this debate because it is all of our opinions. And I wouldn't feel comfortable starting a rookie like Micah. Maybe Dobbins could fill in, but if Crowder shows he can't get on the field this year we will need to bring in a starting caliber player next year to fill his spot.
