C Zach Shackelford
This is an interesting question, because several names come to mind - including WR Collin Johnson, WR Devin Duvernay as well as RBs Chris Warren and Kirk Johnson.
But outside of QB, there's no more important position to the offense than the offensive line. And Zach Shackelford is taking over the middle of the line, the mission control.
No one will appreciate the good work Shackelford does if things run smoothly and two backs end up as 1,000-yard rushers. That's just the life of an O-lineman.
But Shackelford brings an old school toughness and grime to the position that has been sorely lacking. He's smart and coachable and has been working his butt off in the weight room.
If things go as planned, and Texas' offense takes off, at some point over the next four years, Shackelford will work his way into being an all-Big 12 performer.
And that's why he's my breakout offensive performer in 2016 - that and his HS coach at Belton - Bob Shipley - told me a scout told him Shack "has an NFL ass."
"Whatever that means," Shipley said.
RB Chris Warren
There are a number of offensive players who are poised to potentially have breakout seasons in 2016. I'm going with running back Chris Warren.
Warren spent the majority of 2015 buried in the depth chart, which is still a bit of a questionable decision when looking back at it.
But when he was called upon to start the final two games of the season, he did more than just deliver. He shined.
Warren now enters his sophomore year as one of the go-to running backs for the Longhorns and I fully expect him to continue where he left off last season as one of the top offensive playmakers for Texas.
If Warren stays healthy, I see him breaking more Texas rushing records during his sophomore campaign.
