Maybe I am looking through green colored glasses here, but this is something I have felt for a long time...long before the changes of this past summer. I think Rondo was held back a lot by Doc and Pierce. I think Pierce and Doc (KG less so) had a lot of trouble letting Rondo take the lead, and it led to a real power struggle which killed the chemistry of the team, and led to Rondo underperforming.
I really believe that, if Rondo can come back fully healthy, he will thrive on this team. I just think that the leadership dynamics are so much better now, and he that it is truly his team. Stevens seems to be much more willing to share the leadership, and is not as threatened by it than Doc and Pierce, and I really think they will work well together.
