As much as Rondo's aggressiveness decreases in the fourth quarter I think the entire team goes into a hero complex form of basketball late in games. Off the ball movement grinds to a halt. The ball sticks in everyone hands, not just Rondo's. Three point shooting, even early in the shot clock before trying to set up a play happens, as does the hero pass, the hero shot, and the hero iso.
The entire 4th quarter offense late in games is pathetic and it's not just because Rondo's man goes down into a zone and plays for him to shoot outside.
The plays that are run take forever to get going. They slow the pace down to a crawl to help the tired older legs of Pierce, KG and Allen. Pierce goes crazy with some ridiculous isos and then ends up losing a lot of turnovers. KG becomes tight outside and doesn't go down low and establish position as much as he should and as I said before, the off the ball movement by EVERY SINGLE PLAYER ON THE TEAM is pitiful.
