Zizic is coming and he should be able to provide some help.
The rest depends on what other moves we make and how much cap space we will have.
I agree with Dennis 998, Griffin is an interesting addition. He still is a top 20 player IMO. ofc Horford would have to play center in that scenario.
Greg Monroe is another big that will be available. His game is more traditional (reminds me of bigs from the 90s), and he has been a bit disappointing in MIL. But still an interesting option.
Other than that saltlover is always able to come up with good ideas, some weeks ago he had come up with a list of bigs we could get in exchange for Bradley.
