I'm not sure I buy the much better talent argument. can do a deep diver later, but the rams always had talent and were always acquiring talent. and the lions are loaded.
The lions had better talent then the cowboys for a couple years that's for sure however the two years after the superbowl they were bad. Key departures, retirements, tons of injuries(**** happens). They started 11 different lineman one year. Then they started rebuilding again.
Just because a team gets top picks for years doesn't make them loaded with talent. Bad drafts, poor player development, coaches, culture. Have seen this with numerous teams through the years. Did the lions have talent? Sure but was nothing ground breaking.
Then ownership changed or we'll moved to another family member if I recall correctly. Would have to verify. Then they picked up tons of talent st brown, Gibbs, Hutchinson, Williams, Sewell and etc. Culture changed with new ownership along with a coaching change. Granted I think Dan Campbell is more of a culture guy then X and Os
