Kornet signed an Exhibit 10 contract with Boston on Wednesday, according to Chris Grenham, meaning he’ll be around when the team starts training camp in a few weeks. Chances are he’ll end up in the G League with Maine, giving Boston a “Break glass in case of emergency” option at center should the need arise during the regular season. Kornet blocked 25 shots in his 18 games for Boston, and was one of the few bright spots on an otherwise dismal defense to close the season. Boston has one more of those to offer up after locking Sam Hauser into a two-way spot earlier this offseason.
