Knowing what we know now, that's a fair assumption.
Circumstances over the coming season could dictate otherwise. There are plenty of known unknows. For instance, Rodgers sustains another serious injury, the team tanks, the scouting department identifies a Luck-type "QB of the decade" that falls to their pick. Conversely, the Packers win the Superbowl in 2019, and the #1 QB on their board makes a Rodgers-like fall to #32 because, this time, that guy is too tall and immobile as the copycat league tries continues to hunt for the next Russell Wilson.
Or Rodgers is fit as a fiddle over the next two seasons, the Packers win the Super Bowl in 2020, and Rodgers is extended to pick up cap space in 2021 pushing a big slug of dead cap into 2022 and 2023. The possibilities are endless. Or you could make a misjudgement with that draft like Kizer being a "first round talent" taking you to an as yet unscripted Plan C.
The point being, sh*t can happen, good and bad, but as it stands now Rodgers' dead cap/savings in the 2022 season makes turning the page in a 2020 draftee's third season a plausibility even if unlikely based on what we know now.
This is just another one of those situations where making a projection is beyond the reach of even the front office. Various "war plan" scenarios can be scripted out but that's as far as far as it goes. There can be a kind of war that was not unanticipated or no war at all.
