In June 2000 Walsh was diagnosed with renal cell carcinoma (cancer of the kidneys). Knowing that his time may be limited, he hand-selected the coach he wanted to take over the team were he unable to continue. Always known as a fiery coach, Walsh surprised some when he selected mild-mannered UMass Lowell River Hawks coach Tim Whitehead (Hamilton '85). Whitehead earned his graduate degree in education at the University of Maine approximately 10 years prior, and during this time he worked with Walsh as a graduate assistant coach.
