is there any relatively easy way to find players that have never been used?...Other than clicking them one at a time.

I had a theme league many years ago based on a similar idea. I sent a ticket asking for a list of little used players (think I did 10 or fewer seasons) and Admin sent me the list. I don't know how successful you'd be trying that now since there's apparently only one guy handling all the tickets and he might be too swamped to do this, but it's worth a shot.

You better not take credit for John Knight. I found him first!!!

What a coincidence. I just posted a team utterly full of virgin berths in an exhibition season. Merry Christmas! I intend to play them as a team in an Open League just afterward (my hands are full, right now). Maybe after the OL season, I'll paste their roster here. (Intending on a winning season with them, along with a bit of help from prospects.)
