Doubt Rollins makes the roster.
I think Allison makes the roster, primarily because he knows the playbook so well. Rodgers trusts him. The rookies might have more talent, but if they don't know the plays, they won't see the field. So as of now, unless Yancey or Clark really surprise, Allison is a pretty good bet to be on the opening day roster.
WR:
Adams
Cobb
Allison
Moore
EQSB
Clark/Yancey/Davis
Typically WR's show you what they have by their 3rd year. If Davis doesn't show it, then he's gone. But I don't know if we have a returner to replace him...Jaire Alexander can do it, but you need at least one more. Maybe Ty Montgomery can do it. Not sure who else on our roster has the capability. So if we don't have a suitable returner, I imagine Davis makes the roster again. Could also see EQSB not make it. He's so boom or bust to me.
