Not sure what the big mystery is here ... he's just plain been getting the rest of the team involved more.
Have you noticed the huge improvement in bench contributions?
The intensified defensive effort he's giving, and the energized team?
The involvement and chemistry developing between the entire team?
The more clarified roles and limited rotaion combinations?
He has purposely taken less of a scoring role in order for this team to become more complete and cohesive.
He's also a in a slight funk, but that happens, and will correct itself.
Hopefully he's not reading the blogs much, cuz the number of absurd trade threads would discourage anyone.
Man, this team is finally coming together in a big way, and people are still not encouraged or satisfied, and can only focus on the negative.
Personally, I completely understand his lower numbers and realize it's a necessary part of bringing this team together right now ... it will change as the team solidifies even further, and Rondo will be the balanced player he has been.
