"That's a thing we had to work on with Mike. His body language wasn't always showing confidence in other players and confidence in the play that was called," Phillips said. "We have had to work on that and he's now ahead of where he was in the spring. It showed up in the spring game and he's way ahead of that."
Phillips says Hartline has also added to his passing arsenal to where he can now throw the back shoulder fade, a route he couldn't complete last season or in the spring.
"I think a lot of the reps we have got has helped him. He couldn't make that throw last year or in the spring. We saw (backup quarterback) Will Fidler make that throw a couple of times in the spring game and Mike didn't make it. I think seeing Will make that throw made Mike know he had to come up with that in his arsenal," Phillips said.
"The other thing he is doing is he is throwing the deep ball well, too. If you are able to throw the deep ball well and the back shoulder fade, it sometimes is impossible to defend, then you become a much more efficient quarterback."
