It's 2023. Inflation is 69% a year. $9M is tinkering for most teams.
I dunno, I don't think the front office is incompetent. I doubt they bid against themselves. Wil Myers got $7.5M, Carlos Santana got $7M, Jean Segura got $8.5M, Adam Duvall got $7M, David Peralta got $6.5M....
Toronto might have thrown an extra $1M or $1.5M at Belt to get him to sign.
