Louisvilles Peyton Siva coaches his team against Virginia in the KFC Yum! Center Tuesday night. Jan. 13, 2026 | USA TODAY Network via Reuters CoLouisville legend and current assistant coach Peyton Siva is leaving U of L for a spot on Rick Pitinos staff at St. Johns. Adam Zagoria was the first to report the news. In New York, Siva will replace assistant Greg Youncofski, who left St. Johns in the spring to join Richard Pitinos staff at Xavier. Hell also have a reunion with former Louisville assistant Steve Masiello, who serves as both associate head coach and interim general manager for the Johnnies. Siva had been preparing for his third season on Pat Kelseys staff at Louisville. After a stint as the programs Director of Player Development/Basketball Alumni Relations, he was promoted to full-time assistant before the 2025-26 campaign. Siva has specialized in working with U of Ls point guards and also was tasked with instituting a press last season.There is a very real chance that Louisville could face St. Johns in the second round of the Players Era Festival on Thanksgiving Day in Las Vegas. As someone who loved Peyton as a player and loves him now as a person, this is tough news to stomach. Seeing him in St. Johns gear is going to be a bit of a dagger to the heart. At the same time, taking the opportunity to learn under the man who has produced perhaps the greatest coaching tree in the history of college basketball is a move thats difficult to be overly critical of. While the move is understandable, the timing is tough. Louisvilles fall semester begins in just a couple of weeks, and the available (worthy) candidates to fill in as a full-time assistant on the staff of a top 15 preseason squad are few and far between at this point. Best of luck to Peyton with everything moving forward except on Thanksgiving.
