Asked about Frazier, Loeffler responded, "With young guys there are times you go ‘wow,' and like all of our young quarterbacks now there are times when you go ‘wow, we are really making progress,' then we take a few steps back and then we improve the next day so we are bouncing.
"That is normally what happens with young guys," he said. "There are times we look like we know what we are doing, there are times that we have some inconsistencies. With age and experience, with reps, that will improve."
Clint Moseley, the junior quarterback with a sore arm who ended the 2011 season as the starter, only played in two series in the scrimmage on Wednesday and was in for just one series with the ones.
Loeffler said that there is still competition for starting spots across the offense even though the opener vs. Clemson is a little more than two weeks away.
"The sooner the better (on naming the starters), the more continuity you can bring," he said. "We are still not quite there yet at certain positions that in the back of our mind we think we know. The sooner the better. We are working to get to that spot."
Loeffler added, "There are still some question marks. You don't want to jump into a decision without thorough investigation, thorough evaluation, especially in some critical positions on the field."
The coach noted despite not settling on his starters, the Tigers have been doing some game-planning for their early season opponents.
Commenting on the Wednesday night scrimmage he stayed in theme about the need for more consistency although he said at times the offense did a better job of running the football and protecting the passer.
The receivers, an area of concern going to preseason camp, are improving, he said. "To single someone out would be unfair, but I am impressed with the way that group has come along, particularly with their perimeter blocking and ability to make a play," Loeffler said.
Loeffler, who plans to call plays from the pressbox, said the offense will go into the opener with the players knowing what to expect in every situation. Part of the preparation for that took place on Wednesday night in what was a situational scrimmage.
Loeffler said the competition on the offensive line has him "really, really excited." The coach added "We have constantly been changing the lineup. That is by design to try to find the best match we can have on the field to give us a chance. I am really happy with them. They will continue to grow. At the end of the day I think we are going to have a great group at that position."
