Courtney Lee was afflicted with rookie-itis.
As Kareem Abdul-Jabbar correctly observed, Howard's post-up moves were indeed predictable.
Rashard Lewis tended to vanish at inopportune moments.
Their S/R defense was hampered by Howard's disinclination to show with force on the weak side. Also by the hesitancy frequently evidenced by both Lewis and Turkoglu when playing weak-side defense.
When driving into the lane, Pietrus had eyes only for the basket.
When Howard attacked ball-penetrators, the utter lack of protective baseline rotations behind him allowed the Lakers to convert on numerous easy putbacks.
When their perimeter shooters were pressured, Orlando lacked alternative ways to juice their offense.
Lewis didn't get enough shot opportunities, i.e., post-ups and isolations.
The Magic failed to execute at both ends of the court during end-game situations, and this is where their lack of championship series experience hurt them the most.
Most often, teams have to lose in their initial appearances in the Finals to fully understand what it takes to win. Yes, they played well in Games 2, 3, and 4, and Magic loyalists will claim that they coulda/shoulda/woulda won had this shot been made or that shot been missed. But, as the old adage says, "Close only counts in horseshoes and hand grenades."
What, then, does Orlando require to get over the top next year?
In the end, the final verdict is as simple as this: A great team beat a very good team.
