"Watch this footwork," Rivera said.
In team drills, Newton takes a five-step drop and quickly delivers an 18-yard strike to first-round pick Kelvin Benjamin on a deep dig route, hitting the wide receiver on the proper shoulder. Next, Newton takes a five-step drop and goes through his progressions, working right and then all the way back to the far left, hitting Benjamin again on a sideline route. The entire drive is clean and crisp.
"Watch this here," Rivera said as Newton barks for tight end Ed Dickson to shift before the snap. "He's getting the guy lined up. A year ago, he wouldn't have done this.
"But it is his mechanics. They are so much better, his footwork is better and his decision making much better. You sit here and watch him and that is most interesting."
It's a few weeks old but it's a good read.
