In the past two games, Newton is 35 of 43 for 464 yards with four touchdowns and no interceptions as the Panthers (3-3) have won back-to-back games for the first time this season.
"I feel like I am progressing," said Newton, who is 16-22 as an NFL starter.
Newton said he believes he's making better decisions, although he chided himself for taking sacks on two plays that essentially ended drives.
"I've got to throw the ball away," Newton said. "Just give my guys a chance and when we do that, it's exciting to watch. Anytime I have got an opportunity to give a dink or dunk to these guys, they make the big plays."
"I'm not going to deal with hypotheticals until I find out what's going on with him," Fisher said.
They were flagged for five personal foul penalties and defensive end Chris Long was ejected from the game for throwing a punch after one fracas involving more than a dozen players.
Long admitted after the game he lost control of his emotions and said he apologized to his teammates.
"Having to watch the rest of the game in the locker room was probably one of the low points of my career," Long said. "I can't let that happen again. ... I need to be stronger than that. I play this game with a lot of emotion. I won't change that. I can't let people provoke me."
Mitchell, a free agent pickup, was instrumental in the Carolina win.
"We wanted to do a better job of being more mature, being the more composed team," Mitchell said. "We had the game in hand and we could tell by the way they were playing that they wanted to get somebody cheap, try to get us a penalty, something like that. We weren't going to give it to them. We just needed to stay disciplined."
It was a rough day all around for Bradford.
The Rams threatened to tie the game early, but failed to convert on fourth-and-goal from the 1 when Bradford was pressured into an incompletion.
After the teams traded field goals, the Panthers took a 17-5 lead just before halftime on a 1-yard plunge by Tolbert.
Down 20-5, Bradford connected with Quick on a 73-yard completion, setting up a short TD pass to Zac Stacy to trim Carolina's lead to eight.
But Carolina came right back as Newton drove Carolina 72 yards, hitting Steve Smith for his 800th career reception, a 19-yard touchdown for a 27-12 lead.
The Panthers have a chance to get above .500 for the first time since the end of the 2008 season when they travel to Tampa Bay on Thursday night.
"He has done a great job," Rivera said. "You talk about things that he does and his reads and learning to go through his progressions the right way. ... When you see him doing those types of things to give us a chance to win, you know that he has matured."
