It came together, but they had to fire Murray, and replace Gagne, and Penner couldn't score, and they didn't have enough on the bottom lines. Getting Carter couldn't have been part of the plan. Unless they knew he was going to cry about being in Columbus, and could get him relatively cheap. And had Gagne been healthy, and if Penner could score, do they even get Carter? They had already given up a 1st for Penner, and Schenn and Simmonds for Richards. They were depleting a lot of what they had. The day they got Carter, they were tied for 8th in the West, and closer to 13th than 7th.
Between hiring Sutter, and getting Carter, the Kings were 9th in the West. After getting Carter, they were tied for 2nd in the West, and tied for 5th overall. That's very good, but it's not go up 3-0 in every series good. No team, other than the 2012 Kings, has ever done that.
The plan wasn't working that year, and that's why DL had to hire his friend off the farm. Neither Carter nor Sutter were part of the plan. After trading what they did for Richards though, they couldn't miss the playoffs with everyone keeping their jobs. They were out of a playoff spot as late as during the last week in March. If not for a terrible end to the season for the Stars, they may have made it over the Kings.
