Circumstances that increase our chances at Dorsey/Ellis

I think our best chance is if either Dorsey or Ellis (it will be Ellis, stop kidding yourselves) falls as far as #8 and we talk to the Ravens into a trade to keep the Bengals from getting him at #9. I'm guessing we'd only have to sacrifice our third round pick to make that move so it wouldn't be crippling to our draft to do so.
Even then, that's only if both aren't gone by #8, which I think is still pretty likely.
