Yahoo Sports reports: The New York Knicks’ first NBA championship in 53 years may have been built on many things: Jalen Brunson’s brilliance, Mike Brown’s steady hand, a suffocating defense and a healthy roster when it mattered most. According to much-maligned team owner James Dolan, it may also have required a little self-denial. A video released Monday by the Roommates Show podcast revealed that Dolan urged Knicks players to consider abstaining from sex during what he anticipated would be a 10-week march to an NBA title, part of a broader appeal for sacrifice delivered shortly before the playoffs began.
