I think people underestimate the ability to spread out large contracts and buy time before cap hell arises. The Lions will still have a 3 to 4 year window after they decide on their future QB and pay him, extend Sewell, and extend ASB. They also have an advantage in drafting well in the later rounds and developing solid players so they aren’t in a terrible spot if they choose to move on from players that you’d ideally like to extend like a Jonah Jackson or Alim McNeil for example.
