I know it's an edited version of a paper, but no, it's a rambling article that I would call far from "excellent".
I personally find Allan a very grating character - and certainly I don't understand why he continues to work in a sector he seems to find appalling. I am sure I could find him more convincing if he actually left the Australian university sector and wrote his criticisms from outside of it. Preferably from another country, since he seems to rate them much more highly.
That said - yes, his criticisms of the number of law schools and graduates pumped out by them, and the way they study now, sound all entirely valid.
His generic criticism about how and what they are taught, however - I very much doubt he is someone I should pay attention to in that regard.
The path to how we got to the strange and dubious changes to tertiary education generally in Australia seems to me to be complicated and leave plenty of room for criticism of both Left and Right for each being a bit conned in their own way by a self serving education sector. But given the recent debacle of the private vocational education players, I have a bit of trouble with listening to critiques from the Right on anything to do with education.
