Rondo hasn't been consistent? Yeah, I guess if you ignore the first two+ months of the season.
12.4 points/4.4 rebounds/12.9 assists/.493FG%
13.3 points/5.7 rebounds/10.1 assists/.485FG%
14.3 points/6 rebounds/9 assists/.488FG%
13.6 points/6 rebounds/11.7 assists/.533FG%
12.9 points/4.3 rebounds/10.9 assists/.457FG%
National TV (5 games played):
16.2 points/8 rebounds/10.6 assists/.522FG%
So yeah, he usually does play better when he's in the spot light, but is it really that big of a difference? Two or three points more than his average is not a lot, and his assists are actually down...and I would never expect him to average 8 rebounds/game over a season. The narrative that Rondo only tries when he's on National TV or against a good team is so overblown and hasn't been true for a long time.
I won't deny that Rondo's been struggling on the defensive end this season though.
