Their official site has Hearst listed as the #2, so I'd go with that. I'm guessing he would go in if Droughns were hurt. We don't know what the Broncos will do near the end of the year, though. Here would be my guesses...
If Denver sews up a playoff spot early, they will probably phase in Tatum Bell for a few games just to get him some experience. Whether he would be the starter in those games, who knows.
If Denver is still fighting for a spot or some sort of home game, I doubt they would take out Droughns unless he was hurt. At that point, Hearst would probably be the most logical choice.
I guess I'm saying this: keep an eye out for how the Broncos playoff push is going. If they are locked in, you might want to pick up Bell for the fantasy playoffs. But for right now, Hearst is most likely the guy you should have.
