Possibly, but a 130 WRC+ CF with plus D (not elite D) is a pretty valuable asset, regardless of how many other options there aer in free agency at the same position. LIke, I dont really see any of the SS available this year taking less than market value just because there's 4 of them available - unless they are willing to take hometown discount or AA hypnotizes one of their agents.
Actually, looking at the last few seasons, Nimmo is basically Springer, only a few years younger. 20-25 million per year is probably what he should be getting. Probably on a 6-8 year length. Springer signed his 6/150m at age 31, Nimmo is 29. 8 years and around 200M would not be shocking at all
