Yes, Lofton and Moss were superstars, but Lofton wasn't traded in his prime and Moss was a malcontent. Not the same situations.
I'd say your expectations are a little high. If Amari can make another pro bowl here as Lofton did, that would be amazing. I'm not expecting that.
Kincaid is the "star" of this receiving group, but we lacked balance with Keon's inexperience and whatever we were getting from Mack/MVS/Samuel. Amari provides balance. I think what we're going to see is exactly what was advertized in camp: everyone eats. Kincaid, Shakir, Cook, and Keon's receiving production will improve as a result because the defense now has to guard all areas of the field.
