"Each one is its own miracle, so it's kind of amazing how over time they add up," said Magee.

For Scott and Jacob and their families, it's a Christmas gift they'll never forget.

"It's hard to express how much we're grateful," said Kelly.

"I don't know if you can ever fully realize what you do for another family," said Denise.

Both boys are recovering well.  Doctors said Scott can return to sports as soon as he's ready, even football.  If all goes well, his new liver could last the rest of his life.  Scott wants to encourage other people to consider becoming organ donors.

"I think more people should sign up to do that because it helps a lot of people," said Scott.

Transplanted kidneys don't last as long as some other organs, so Jacob will likely need another transplant in the future.

Jacob said he is sorry for the donor family's loss and wants them to know.

"I'm incredibly grateful since I got this wonderful gift," said Jacob.

Magee said that single donor likely saved many more people in addition to Scott and Jacob.  Counting organs and tissue donation,  anywhere from 7 to 30 patients may have been helped.

"Both Jacob and Scott are living proof of how big a difference it makes," said Magee.
