I don't totally disagree with your statement but in my opinion, while they both may be let's just fruits, they are not the same. BM is a DAvidson Legend and a recognized name in western Carolina and the extended region. MM played for his dad, spent 1 year as assistant away and then was handed the reigns' to a successful program his father built after sitting on the bench with him for 14 years. PM SR is not only a Philly legend but a basketball legend. PM JR like MM played for his dad but PM JR got his 20 years of assistant experience from coaches other than his dad and Has HC experience.
IMHO, PM JR is better positioned for success and PM SR has better visibility in the basketball community. Now none of this means I expect PM SR to perform magic but if he were a magician, he would be better known and experienced than BM
