If that's what you're taking from it, I didn't write it well enough.
Though you're right, I guess. Dodge is the WK-based Durango, L-series Charger and Challenger, and J-based Journey, while Chrysler is the Pacifica and 300. Am I forgetting a Dodge?
I think the goal, though, was to replace what needed to be replaced and refresh what needed to be refreshed. Fiat starved while Chrysler, Dodge, Ram, and Jeep were refreshed or rebuilt. Chrysler and Dodge starve while Alfa Romeo, Ram, Jeep, and Maserati are being rebuilt.
Unless they destroy the identities of the brands, there is not enough people and money to do it all at once.
I think SM also was following the Kaiser idea of avoiding market fights where possible and staking out niches.
