They're showing up because someone made an offer for them. All players with pending offers will show up on the negotations list regardless of skill level.
You can make an offer for a lot of players you can see (CL opponents, league opponents, cup opponents, friends, maybe even freinds opponents ... I don't know what the rule is though .. sometimes players of same skill level on same squad you can offer for one but not another ...
Also, I think only your reserve players (1 SP away from a star) show up on negotations list if they don't already have a pending offer.

"They're showing up because someone made an offer for them"
my neg list looks exactly like Morgan's...and i am on a server with people with level 6 (i am level 4, Dreamer) so there are much better players available on the server so ours aren't the best.
Many of these players on the neg list are unbidded on. I just checked a 36 star guy, no bids. So he can't have shown up becoz someone just bidded on him (coz he's still on the neg list 10 min later without receiving bids)
