Not to mention Collison and Rondo do not play well together. Collison is not a great off the ball player (the type of player that Rondo excels with). Those two should not be seeing significant court time together, but here we are.
That's the big thing for me. Rondo and DC are both players that can really help the team but they don't mesh well at all when playing together. Strange because he and CP3 played well in LA. Maybe it will take time to get them clicking but in the meantime the 2 PG lineups aren't paying dividends.
