Law practice: are lawyers good writers?

When I was a full-time practicing lawyer, I thought I was a good writer. I believed I was above average within the profession. Now I see that I was quite mediocre, that I was poorly educated about the standards of high-level professional writing, and that I was ignorant of my own limitations.

Was I unique?

Many practicing lawyers today believe themselves to be good writers, above average within the profession. Are they? Or are they as I was--ignorant and uninformed?

I am not being smart here; I really want to know.
