Because the Vikings didn't choose Pace, Pace choose the Vikings. He was the top UDFA that year and he came to the Vikings because they had the worst LB group in the league. It was easily the best place for him to score a job.
I don't hate Adofo-Mensah, but I don't agree with his roster building. If this team is supposed to be taking a step back this year, why are they still the 7th oldest in the league?

With the Vikings front office, it's really a similar argument as the Twins. Way too reliant on average-at-best veteran players and they either won't, or can't get enough young affordable high-ceiling players to build a sustainable contender.
The 2024 draft was much better, so if things drastically change soon, I'm OK counting the last two years as a learning curve error or ownership meddling. But they really have to start building through the draft not free agency. I'll give it until next year before I suggest we need to do something new.
