"You get a whole sense of it and just him and the kids ... that he was trying to be strong, but it's a situation I can tell how he feels," Johnson said Thursday after practice. "I lost my grandmother earlier in this year and just knowing how that feels I just kind of wanted to do something to at least try to lift his spirits."
Johnson also became a father earlier this year with the birth of twin boys. He said that just made him appreciate his sons even more. He said he sent a few Christmas gifts to Jack McDonnell and the family, and he also shared his telephone number in case they need anything that he might help with in the future.
The Titans running back said he still plans to auction off the shoes to help families. But he sounded reluctant Thursday as he discussed the shootings.
"I kind of want to step back," Johnson said. " ... I kind of did it for the kids and the family. I really don't want to make it about me."
"It just came to our attention that one of the individuals who was one of the victims up there was an avid Dolphin fan," coach Joe Philbin said Thursday. "We just thought it would be the right thing to do."
