I really do think they were targeting Tebow.
First off, Buddy Nix said that the player was taken when they wanted to move up, and that could mean they wanted Baltimore's pick and Denver beat them to it.
2nd, Ralph said that Baltimore 'panicked' Translation: Ralph and the Bills offered a lower package to the Ravens to move up to get Tebow, Ralph threw a hissy fit, and spat off about the Broncos.
Dan Williams was STILL on the board at this point, so it cannot be him since Nix said the player was taken.
