I mean he was flat out better than everyone else in this class. And just the nature of FA, you're going to overpay for literally every single guy who isn't a max contract player. So if you're going to invest, may as well slightly overpay for a dude who's actually super impactful towards winning.
Also just seems this range is where a top 75-ish player gets paid now. Huerter/HB/Hart/Brooks/Cam Johnson etc. All in that 17-22 mil/season range.
