On this day: Kevin McHale gets 56; Sam Cassell signed; Jayson Tatum born

On this day in Celtics history, legend Kevin McHale scored 56 points, Sam Cassell signed with Boston, and Jayson Tatum was born.

On this day in Boston Celtics history, champion reserve guard Sam Cassell signed with the storied franchise as a late-season addition in the Celtics’ push for Banner 17.

Cassell had played just under half — a total of 38 games of the 2007-08 NBA season — with the Los Angeles Clippers before he managed to negotiate a buyout at the end of the month of February. After listening to the pitches of several NBA teams, Cassell ultimately decided to hitch his proverbial wagon to the team, inking an agreement as an unrestricted free agent on this date in 2008 to finish the season in green and white.

The Florida State product would play an important role for the Celtics in the postseason, and after being reunited with former teammates Kevin Garnett and Ray Allen won his third and final title.
