My thoughts exactly. Since Croom has been here, he has not as of yet had the break out game one would expect him to have. The eye test made me think he could be a dominating receiver. The reasons could be learning a new scheme, the quarterbacks, or competition from the other receivers.
However, with Kamara coming in, this could be a psychological boost for him. And AK being reunited with JC could be very positive for him as well. Old HS teammates on the same college team sometimes can be greater together than apart.
I look for Croom and Kamara to push each other. And with the competition each will face within their position groups, they will need it.
