Contract errors I've noticed so far (sourcing Cot's for all noted errors; will either edit or post separate updates):
Phillies
-Andrew McCutchen is in the final year of his deal, making $20M
-Odubel Herrera's contract for 2022 is not guaranteed. He has a $11.5M team option for 2022 and a $12.5M team option for 2023
-Scott Kingery's 2024, 2025 and 2026 contracts should all be team options (not just the last year)
-none of Matt Joyce, Brandon Kintzler or Ronald Torreyes are guaranteed deals just yet. Kintzler's is worth $3M if he makes the team; I don't know for the other two, but they shouldn't be on the payroll yet (unless that's just the AI)
Diamondbacks
-Ketel Marte's last 2 years should both be team options; as of now, only the last one shows up that way ($1M and $1.5M buyouts, respectively)
-Eduardo Escobar is making $7.5M, not $7.7M
-Kole Calhoun should have a $2M buyout on his team option (unless buyouts are being ignored

)
Braves
-Ronald Acuņa Jr.'s last two years should both be team options; as of now, only the last one shows up that way ($10M buyout on year 1; unsure of the second)
-Ozzie Albies' last two years should both be team options; as of now, only the last one shows up that way ($4M buyout on year 1; $0 buyout for year 2)
-Josh Tomlin has a $250K buyout on his team option
