The Celtics struck out at trying to trade for Pelicans star Anthony Davis and were unwilling to part with young wing Jayson Tatum.

Horford, 33, has one year remaining on a four-year, $113 million deal and a player option he may decline for the 2019-20 season worth $30.1 million. It is unclear how the possible departure of star point guard Kyrie Irving could impact Horford’s decision.Horford averaged 13.6 points, 6.7 rebounds and 4.2 assists per game in 2018-19 and is expected to have a slew of options should he become an unrestricted free agent.
