The NCAA investigation isn't the only reason for concern in Chapel Hill.
There's a quarterback controversy, and veteran starter T.J. Yates wasn't shy in his response about the possibility of sharing time with backup Bryn Renner.
"I wouldn't like it, but whatever Coach Davis feels is right, I've got to go with it," Yates told the Raleigh News & Observer.
He shouldn't like it. It's not a good idea. Just ask Jacory Harris. Or Tyrod Taylor. Both of those players were stuck sharing time at the beginning of their careers -- Harris with Robert Marve and Taylor with Sean Glennon. Harris told me once that he felt like he had to be "the savior" every time he came in the game, and there was no margin for error. Using two quarterbacks has both constantly looking over their shoulder. It's too much pressure. It gets them out of their rhythm. Pick a quarterback, invest in him, and make it work. If it doesn't, then make a change and stick with it. Otherwise, the offense will continue to stop and start just like the quarterbacks who are trying their best to run it.
