Clingan got in foul trouble plenty his freshman and first half of 2024. His freshman year he had some high foul rates (f/40 min).
Spencer not only was a big part of the 2024 title run with his play on the court, but one of his biggest contributions was cursing Clingan out for committing a dumb 2nd foul in the first half of one of the Big East games (don't remember opponent). Ever since Spencer did that, Clingan stopped getting in foul trouble for the rest of the 2024 year.
2023 Sanogo/Clingan > 2024 Clingan/Johnson, so foul trouble was more detrimental in 2024. A perfect example of that was the game against Creighton in Omaha. UConn was doing fine at the start of that game, but as soon as Clingan picked up that 2nd foul (bogus call, Ashworth flopped) the game completely changed after that.
