I think Morgan has been good. I think after 2019 most expected more that we have seen, maybe we will get that in 2022, I hope so. If not I hope there is another QB that can play.
As far as the question - I think AAK and probably AW was a more talented QB, but had a much poorer supporting cast around them both. AAK was a dual threat, good arm QB that had no defense and a much weaker WR group. He did have some great RBs though.
If I had to rank the QBs over the past 20+ years I would go:
AAK
Weber
Morgan
Cupito
Leidner
The rest
