Mark Carlson becomes USHL's all-time wins leader with 779th victory

Mark Carlson reached a new USHL benchmark on Oct. 3, 2025, winning his 779th regular-season game in his 1,500th contest and moving past P.K. O’Handley for the league’s all-time victories lead. Cedar Rapids’ win over Waterloo gave the RoughRiders coach the record outright and put his name at the top of a list that had stood at 778 wins.

The milestone carried extra weight because Carlson had already passed O’Handley’s 1,476-game mark for regular-season games coached on Feb. 15, 2025. On Feb. 11, Carlson stood at 765 career wins and 1,471 games coached, meaning the race to the record was tightening one night at a time rather than through a sudden surge. By late September, he had tied O’Handley at 778 wins before the Oct. 3 victory pushed him alone into first place.

That kind of climb matters in the USHL because the league is built on turnover. Players move through quickly, rosters change year to year, and the best coaches have to replace talent while preserving an identity that can survive those changes. Carlson has done that in Cedar Rapids longer than anyone else in franchise history: he has been the RoughRiders’ only head coach, turning the bench into the most stable position in one of junior hockey’s most fluid environments.

His 2025-26 season reinforced that case. Cedar Rapids finished 36-17-3-6 and posted a .653 winning percentage, and Carlson was later named USHL Coach of the Year for the fourth time. He had also won the award in 2016, 2011, 2005 and 1999, with the honor voted on by the league’s team general managers. The repeated recognition showed that his value has never been tied only to one roster or one era.

Carlson’s record is about more than volume. It places a long-term program builder at the center of a league defined by player development, quick turnover and constant roster reshuffling. At 779 wins, the number itself is historic, but the fuller story is how he kept winning across 1,500 games and made Cedar Rapids a model of continuity in junior hockey.
