Aikens, his main competition also struggled today. I think the locks are Amendola, Dobson and Boyce. The other 2-3 slots are up in the air. If Edelman doesn't get his ass back on the field, he'll be looking for employment pretty soon after the second exhibition game. Love Edelman's return ability and run after the catch, but you can't beat out other guys if you're not on the field practicing.
My preferences would be Amendola, Dobson, Boyce, Edelman, Aiken, Thompkins. But I have no idea how the last thee will wind up.
