Pat Summitt, the winningest coach in Division I basketball, passed away Tuesday morning at the age of 64. Over the weekend, the Summitt family announced that her health had deteriorated and they were asking for prayers as she succumbed to early-onset dementia, which she had battled since 2011.Her son Tyler announced her passing in a statement:"Since 2011, my mother has battled her toughest opponent, early onset dementia, 'Alzheimer's Type,' and she did so with bravely fierce determination just as she did with every opponent she ever faced," Tyler Summitt said. "Even though it's incredibly difficult to come to terms that she is no longer with us, we can all find peace in knowing she no longer carries the heavy burden of this disease."There will be a private funeral service in Middle Tennessee and a public memorial at the home of the Lady Vols, Thompson-Boling Arena.The list of achievements and awards Summitt compiled over her career are overwhelming and almost obscure the impact she had. She coached Tennessee from 1974-2012, retiring one year after her diagnosis with a 1098-208 record. For perspective, Mike Krzyzewski, who has coached three more years than Summitt did, has 55 fewer wins. Summitt won the NCAA championship eight times, including the historic 97-98 undefeated season, and appeared in the Final Four a staggering 18 times, more than any coach in college basketball history.
