Let's take a look at a hypothetical roster and payroll for 2017, the year the move to Cobb county is scheduled for.
Minor (12M, last arb year)
Teheran (6.3M)
Wood (4M, first arb year)
2 other starters at minimum (total 1M)
Total for starters: 23.3M
Kimbrel (13M)
Avilan (3M, 2nd arb year)
5 other relievers at minimum (total 2.5M)
Total for pen: 18.5M, Total pitching (41.8M)
C Gattis (7M, 2nd arb year)
1B Freeman (20.5M)
2B TBD (0.5M)
SS Simmons ((8M)
3B TBD (0.5M)
RF Heyward (22M, new contract)
CF BJ (17.2M, last year)
LF TBD (0.5)
Total lineup: 76.2M
Bench (4M)
Grand total: 122M
Conclusions:
1) If the farm system remains productive and generates the players I have filled in at minimum salaries, we can sign Heyward for something in the 22-25M/year range and remain under 125M.
2) If the Braves play on a payroll of 120M or less in 2017, we probably can't afford Heyward without moving a significant contract.
3) To be able to afford both Heyward and Justin Upton (or similar players at free agent prices), payroll would have to move above 140M by 2017.
