Johnson will don No. 12 for the C's in honor of his mother, Rhonda Curlin, who wore the number in high school. Moore chose No. 55 to reflect the position in which Boston drafted him on Thursday and to remind himself of the journey ahead.
As part of their introduction, Johnson and Moore handed out 25 Celtics-themed MacBook computers to students at Edison K-8 School and participated in a Celtics trivia contest. Both players also met with the media on Monday.
