Or they just got old. Minus Rose, who had a freak injury in his early 20's.
Boozer averaged under 30 minutes per game under Thibs for 2 out of the 4 seasons he played under him, and the highest mpg he ever played in a season was 32.
Deng was playing heavy minutes before Thibs even took over as HC (Averaged 37.9 mpg the year before Thibs took over).
The poster who said Deng was known as "durable" doesn't know what he's talking about because Deng's miss big chunks of seasons all throughout his career, long before Thibs became HC.
Noah had two season where he played 37 and 35 minutes a game for the year, but besides that never average minutes in the mid-30's or higher.
Were his mpg under Thibs. That's not asking too much from your defensive anchor.
Correlation =/= causation.
You're acting like minutes played per game in basketball is the equivalent to taking handoffs in an NFL game.
