Philly gets easy baskets in the open court because they have young legs.
The Celtics minus Bradley's ball pressure and young legs do not get out into the open court and do not get easy baskets because of it. Ray Allen obviously isn't Ray Allen at the present time which allows hilly to smother Pierce and KG leaving us no viable option in the half court.
Lots of teams have young legs, but getting easy baskets in the open court begins with all five guys playing agressive defense.
For the first half of the year we were an old team playing .500 ball. After Ray got hurt, and Bradley stepped in, we became an agressive defensive team and it opened up our transition game, while getting opponents out of their rhythm.
Steamer, Sasha, Petrius, Dooling all contribute to this type of defense, but in the playoffs their minutes get squeezed, and the team suffers for it.
Now, with Bradley out and Ray back in the starting line-up, we lose that edge, and we're back to being the team we were for the first half of the year.
