On this day: Danny Ainge traded to Kings; Sichting dealt to Trail Blazers

On this day in Celtics history, Danny Ainge was dealt to the Sacramento Kings and Jerry Sichting to the Portland Trail Blazers.

On this day in Boston Celtics history, the team traded champion shooting guard and future team president Danny Ainge to the Sacramento Kings in 1989. The Oregon native had been picked up by the Celtics with the 31st overall pick of the 1981 NBA draft.

But, he was already playing professionally in Major League Baseball and had to be bought out of his baseball contract with the Toronto Blue Jays before he would be able to play for the Celtics. Ainge had been with the Blue Jays for eight seasons, his only pro assignment in any sport up to that point.

The BYU alum won two titles with the Celtics in 1984 and 1986 and made his sole All-Star game with Boston the season before he was dealt to the Kings with Brad Lohaus for Joe Kleine and Ed Pinckney.

On this day: Semi Ojeleye born; Larry Bird triple-double vs. Hornets; Jim Paxson, Charles Smith cut

On this day, Semi Ojeleye was born, Larry Bird hung a triple-double on Charlotte, and Jim Paxson and Charles Smith were cut.

On this day in Boston Celtics history, Jesusemilore Talodabijesu — better known to Celtics fans as “Semi” Ojeleye — was born in Overland Park, Kansas back in 1994. Semi played collegiately at both Duke University and Southern Methodist University (SMU), transferring from the former to the latter in search of more playing time.

There, he would help lead SMU to win the 2016-17 American Athletic Conference (AAC) regular season and Tournament Championships before being picked up by the Celtics with the 37th overall pick of the 2017 NBA draft. He played four seasons with the Celtics before leaving the team to sign with the Milwaukee Bucks ahead of the 2021-22 NBA season.

Ojeleye averaged 3.5 points and 2.1 rebounds per game in his time as a Celtic.

Every player in Boston Celtics history who wore No. 4

Today’s installment focuses on the 30 players who wore No. 4 over the years as of September 2023.

The Boston Celtics have more retired jerseys than any other team in the NBA, but that doesn’t mean the rest of their jerseys have little history or interest tied to them.

In fact, with 17 titles to their name and decades of competitive basketball played in them, their unretired jersey numbers pack in some of the most history not hanging from the rafters of any team in the league. To that end, we have launched our accounting of that history, with every player in every jersey worn by more than one Celtics player in the storied franchise’s history accounted for.

Today’s installment focuses on the 30 players who wore No. 4 over the years as of September 2023.

On this day: Johnson, Jerebko signed; Lee trade; Paxson, Mickey born

On this day in 2015, the Boston Celtics signed Amir Johnson and Jonas Jerebko and traded for David Lee.

On this date in Boston Celtics history, the team signed big man Amir Johnson to a two-year, $24 million contract. The Los Angeles native had previously played for the Toronto Raptors for the previous six seasons before decamping to the Celtics, and the Detroit Pistons for four more before that after being drafted directly out of high school by that team 56th overall in the 2005 NBA draft.

Johnson was a key part of the franchise’s post-Banner 17 rebuild, anchoring the team’s interior as a veteran presence while averaging 6.9 points, 5.5 rebounds, 1.7 assists, and 0.9 blocks per game.

Johnson would leave the team in free agency to join the Philadelphia 76ers in the summer of 2017.
