5 Boston Celtics who definitely won't be back for the title defense

Luke Kornet, Unrestricted Free Agent

Arguably the biggest potential loss on this list would be unrestricted free agent Luke Kornet. The 28-year-old played spot minutes throughout the postseason, but his value would show depending on the matchup the Boston Celtics encountered.

That was on firm display against the Cleveland Cavaliers, when he stepped in to provide strong contributions in multiple games of the 4-1 series win.

True as that may be, Kornet is an unrestricted free agent entering an offseason in which the center position is relatively thin on available players. As such, it's possible that a team will take a chance on him with a contract that exceeds what the Celtics are able to offer.

It would leave a void that the Celtics would need to find a way to replace, especially if Oshae Brissett and Xavier Tillman walk, as well.

Kornet has endeared himself to many Celtics fans during his time with the franchise, which would make this a sad departure. The NBA has seen an influx of high-level big men, however, and Kornet's defensive presence could net him a decent contract because of that fact.

No matter what traspires, Celtics fans can agree on one thing: The Kornet Kontest will live on in Boston fans' memories.
