Harbaugh is somewhat similar to PJ; generally speaking, he's pretty conservative. I've posted this before, but look at Andrew Luck's stats. Harbaugh coached him his first two years at Stanford. At the time, Luck was viewed as a generational-level talent at QB. And even with that, Harbaugh still was conservative and run-heavy. He had a much better Defense and RB at Michigan, so not surprising McCarthy's attempts were lower. Look at Harbaugh's last year coaching Luck (2010) and McCarthy's last year (incorrectly listed as SR below). Same 9.0 Y/A, AY/A is almost identical. Completion % is within 1.6%. I think it will bare out in LA as well. I'm guessing Herbert's attempts and yards will go down by at least 15%, but his efficiency will likely be better. Just the way Harbaugh rolls. But if you watch Michigan football games, you could see he can "make all the throws". His arm isn't as strong as Penix's; however, he can make really tough throws and put it where it needs to be. He can move around the pocket. I watched a decent number of Michigan games, specifically watching JJM a lot, and I always came away impressed.
