(CNN) Miami Heat shooting guard Dwyane Wade is throwing his support behind initiatives to honor the victims of February's deadly school shooting in Florida, donating his time and money in spite of criticism.

"I do more than dribble," he told CNN's Dave Briggs in an interview that aired on "New Day" Monday morning.

Wade donated $200,000 to the March for Our Lives, a student-led march against gun violence that will take place Saturday. Previously, he dedicated the rest of his season to one of the victims , 17-year-old Joaquin Oliver, and gave Oliver's family a jersey and sneakers in the student's honor.

"How can we move on -- as adults, as parents -- when we know our kids are not safe at school?" the member of three NBA championship teams asked Briggs.

He continued, "I can't imagine what these families are dealing with, are going through. But what I try to do is I try to put myself in that situation and the heartache and the hurt, just even trying to imagine it, is too much to bear."
