If Hayward signs a 3+1 max with the C's, it's highly likely he is gonna hit free agency in 2020. That's the year Horford's contract comes off the books.
2019/20 season
Horford $30,123,015
Hayward $32,670,000 (assuming that the cap will be set for $99 million next season)
SUM $62,793,015 coming off the books in 2020.
AD has a player option for 2020/21.
