There are many mock draft simulators available. The general idea of a mock draft simulator is:
* You draft for one team or for many teams.
* Some simulators allow multiple live players.
* The simulator makes its selections based on a player ranking, which it shows you, some random component, and other factors.
* You typically trade with the simulator or with other live players.
NFL Mock Draft Database
www.nflmockdraftdatabase.com/mock-draft-simulator* You can play this year's draft, next year's draft, or previous year's drafts.
* You can draft for one team or for multiple teams.
* Does not allow multiple live players.
* Player rankings for this year and next year are based on MDBs consensus rankings which change as new big boards get added to the consensus.
* Player rankings for previous years can be either the actual resulting draft selections or the consensus rank just prior to the draft (except for some reason, for last year's draft you can't choose the actual draft selections).
* Simulator makes trade offers to you and you can make trade offers to it.
PFF
www.pff.com/draft/nfl-mock-draft-simulator?ref=2717aa6e-ecd5-488d-b20b-336244a6ba82* You need to be a PFF member to get full functionality.
* Only this year's draft
* You can draft for one team or multiple teams.
* Does not allow multiple live players.
* Player rankings are either PFF big board or public? rankings. You can mix between the two.
* Simulator selections are controlled by both the ranking and a set of configurable parameters (positional value, need, and randomness).
* The simulator tells you which teams are interested in making trades with you, but it is up to you to propose the trade. You can also choose to trade with teams who do not indicate interest, but I think you get better terms with teams who do indicate interest.
* Trades may include both draft slots and one current player from the roster of each trade partner, although not players just drafted.
* Allows you to click on draftable players and see their PFF stats and evaluations.
Fanspeak / On the Clock
fanspeak.com/ontheclock-nfl-mock-draft-simulator/setup.php* I think you need to be a member for full functionality
* You can only play this year's draft
* You can draft for one team or for multiple teams.
* Does not allow multiple live players.
* Player rankings are based on big boards. OTC provides regularly updated big boards from multiple persons. You select which big board to use.
* Simulator selections are controlled by both the ranking and a set of configurable parameters (which I do not fully understand).
* Simulator makes trade offers to you and you can make trade offers to it.
* Fanspeak also has a simulator where you act as GM and make trades, sign free agents, draft etc... It is pretty cool, but it takes a while to play one game, and it is not always up to date with roster.
NFL Draft Buzz
www.nfldraftbuzz.com/simulator* You can only play this year's draft
* You can draft for one team or for multiple teams.
* Does not allow multiple live players.
* Player rankings are based on NFL Draft Buzz's big board or on consensus ranking. You choose which.

Pro Football Network
www.profootballnetwork.com/mockdraft* You can only play this year's draft
* You can draft for one team or for multiple teams.
* Allows multiple live players. There are new public drafts starting every few minutes.
* Player rankings are based on PFN's big board. Big board is updated infrequently.

Walk the Mock
www.walkthemock.com/* Requires membership to get full functionality. Its cheap.
* You can only play this year's draft
* Has multiple modes with different functionalities. I usually do trading places = one live player, drafting for one team, with trades.
* In different modes, you can draft for one team or for multiple teams.
* One mode allows multiple live players. There are a few public drafts per day.
* Player rankings are based on WTM's big board, which looks similar to NFL Mock Draft Database.
* Simulator selections are controlled by ranking and randomness factor.
* In trade mode, you can make trade offers to the simulator.
* In multiple live player mode, you can trade with each other.
* They have a mode which allows you to trade against the actual draft - but that is only available on draft day and the few days following.
The Draft Network used to have a nice very mock draft simulator. Then they scrapped it and developed a new version in beta which was not quite as nice. Then they appeared to go out of business. Since they have returned, I don't see a mock draft simulator on their website.
There are a few other simulators which are just NFL Mock Draft Database rebranded.
There could be others.
