Casey has gone through a gamut of emotion from sadness to anger. He hasn't helped but ask himself the impossible "what if" questions either.
What if he hadn't recruited Kellerman to play at MATC?
Would he still be here?
"There are so many things that go through your mind," Casey said. "So many what ifs. You just try to get through those. That's all you can do."
One thing that's for certain, Kellerman had a passion for basketball. A standout at Verona High School, he went on to play at Loras College in Iowa before transferring to MATC. In just his second game, his final game, he lead the team in scoring.
"He showed up big," Casey said. "He went out on top doing the thing he loved. He was able to have a great game. He won't be forgotten. He'll always be in our hearts and a part of the Stormer family."
The Kellerman family has set up a scholarship in their son's name called "Opportunity 34." It will go to a Verona High School basketball player that exemplifies what Will stood for and help them pursue the same dream he had of playing basketball at the next level.
