Mees was a lead anchor on SportsCenter from 1979 to 1987 when he took on play-by-play duties for NHL games on ESPN. ESPN later lost the NHL contract to SportsChannel America and Mees returned full-time to SportsCenter. When the NHL returned to ESPN in 1992-93, Mees worked NHL games during the season and hosted SportsCenter in the off-season. Mees was also the powerful guiding voice of NCAA Ice Hockey on ESPN, and was a forceful advocate to help the growth of the Frozen Four (NCAA Hockey's championship tournament) into its national status today.
On August 14, 1996, Mees, who did not know how to swim, drowned in a neighbor's swimming pool. At first, police said Mees had jumped into the pool to save his daughter, Gabrielle. They later retracted that account, saying that they did not know how Mees ended up in the pool and that Gabrielle had not been in it. He left behind Michele, his wife of almost ten years, and two daughters: Lauren, who was eight years old, and Gabrielle, who was four.
