^^^ You can edit your pre-draft rankings and when the draft happens, the players you ranked (from best to worst) would be drafed automatically... Assuming that said player is available.
Let's you rank Tomlinson, Jonhson and Gore as your top three. You end up with the second pick, and you'll get Johnson (if LT has been drafted) if Tomlinson has not been drafted, you'll get him because he's first in your rankings.
