The NFL is deliberately set up to make it hard to sustain success. Two years back, many of the same people that are currently green with envy over the Chiefs were fawning over McVay and the Rams. One year ago, the 49ers were the darlings on the block with an entire defensive line made up of high first round picks. In five years, I predict there will be multiple threads on a Chiefs forum where posters complain that they have only been good, not great, lately, and that the team has never gotten back to their 2019 form. Perhaps a misguided Chiefs fan will compare them to the Mariners.
Bad teams get high draft picks which are heavily underpaid in the current CBA. The Chiefs winning a Super Bowl with Mahomes under a rookie contract is great for them, but if you are looking to compare how a franchise is being run then you need to watch how the hottest teams every year fare once they have to pay their rookies fairly. The 2019 Chiefs are a poor benchmark for the 2020 Seahawks.
In my view the 2020 Seahawks look to have a solid shot at making the playoffs if a season occurs, and also look to be entirely capable of winning three games in a row in the post-season if they get hot at the right time.
