Sure, junior devs will usually outpace senior devs (especially looking at LOC). But in the end, did they produce robust, reliable, fault-tolerant code that is easy to understand, extend and most importantly delete? I'd like to hear more specifics on this project. Especially why if junior team A and senior team B were already working for 3 years, why was team C introduced? Did they save the day? I'm really curious about the final outcome and any learnings you might have had.
