It is a lot of lottery tickets to give up, plus some cheap contracts, so the next 4-5 years are going to be tough. They had a fairly easy schedule and one of the worst offenses in the league. Sure, the 5 wins they got was maybe a bit unlucky, but it did take a top 10 defense to manage that and defensive performance doesn't have as high a year-to-year correlation as offensive performance, so it might be tough to keep that up. With the Chiefs in the division, it's going to be Wild Card hunting for a while and if the Chargers and Herbert get rolling as well, it could be an even tougher division.
Still, you have to think ownership is thinking more than 2 years ahead on this. If Wilson doesn't turn things around, it might be worth it to just suck for a couple of years and make trades for future picks. Mahomes is only 27, though, so you have to figure the Chiefs are going to be tough for a long while yet.
They gave up a 1st rounder this year and went down by one round from 2nd to 3rd next year. So about average as coach trades go. What they paid for Wilson was pretty steep.
Problem for both Wilson and Payton is that it could hurt the team for the next 3-4 years. And if the team have 3 losing seasons in a row, I doubt either one will be around for the fourth.
