I was a big fan-favorite of PF-David Lee however, when it came to stopping oponents from scoring inside I could never defend or justify Lee's poor defense in stopping oponents from scoring inside the paint. If the oponent miss the shot then Lee will get the defensive-rebound.
Melo & Bargani has a long NBA career of letting oponents score inside the paint, which makes them a liability at PF, especially in the playoff, and in the 4th qtr. of regular season games .. u will see monitor-kicking and fire extinguisher knockouts when things dont go right.
I recall Bernard King diving and falling on top of Dominique Wilkins, which put a stop to Dominique scoring inside the paint LOL
