"Losing bothers me. Coming up short bothers me," Bosh said in a video he posted to social media Tuesday. "It always has, since the moment I started playing basketball and it kind of bleeds over into everything that I do. So I’ll just get ahead of it so you hear this from me. I’m disappointed.”
Bosh holds the Raptors' franchise record for career rebounds and ranks second on the team's all-time points list behind DeMar DeRozan.
The 35-year-old's career was cut short due to a recurring blood clot condition. He last played in the NBA during the 2015-16 season.
This year's Hall of Fame inductees will be announced on April 4 during the NCAA Tournament's Final Four.
