Smith's wife Samantha, tweeted the news Tuesday afternoon.
Andrew peacefully passed away in his sleep and in my arms as I told him I loved him this morning. Love you always, Smith.

Since Andrew, a standout on Butler's back-to-back national semifinal teams, was diagnosed, Samantha has chronicled his valiant fight on her blog, Kicking Cancer With The Smiths.
Big East Coast Bias would like to offer our condolences to Samantha, and the rest of Smith's friends and family.
Rest easy, Moose.
