Austin has an advantage in that I expect him to also contribute in the Lamb's return game and Jones has an advantage because Dick LeBeau will be scheming to free him up in passing situations.
I expect Jones to lead all rookies in QB pressures and sacks.
I wanted to have some original picks for OROY and DROY, but both of my picks have already been mentioned in this thread. I'm going with DeAndre Hopkins and Jarvis Jones. I think they are the most NFL-ready and in the best situations to succeed.
Obviously some of the offensive linemen are just as NFL ready and will start from day one, but offensive linemen never win OROY.
