Except that's not the way they have been doing it. It was like that one practice, but the next day it's different. They have been rotating who goes first in terms of drills or who goes out with the first team. Yesterday, each QB got 5 shots to work with the offense. They mixed it up, but Newton went 1st, 1st, 2nd, 2nd, and 3rd on his stints with the ones. Stidham also went 1st, 1st, 2nd, 2nd, and 3rd. Hoyer went 1st, 2nd, 3rd, 3rd, and 3rd. Basically, Newton and Stidham have been getting exactly the same amount of work with the same players.
I do find it interesting that of the 87 people / places I look at, many of them said Stidham had a better day yesterday. Newton got mostly an "also did pretty well." However, this morning on the NFL Network, they had a pretty decent discussion based on their report that Newton looking confused and didn't know what to do at times in yesterday's practice. I hadn't seen that elsewhere. I am guessing it was Rapoport that must have brought it up. He covered NE for three seasons, so I sort of listen to him on NE stuff (but overall I find he is not always accurate in general).
They went on to say it's still early and Cam will have some growing pains in the early going. The panel universally felt he will end up being the starter. Of course, they left themselves some wiggle room by saying that if two weeks from now he is still looking a little lost, then they may revisit their opinions.
I also watched a segment on Speak For Yourself on Fox, and Emmanuel Acho felt Cam is not on as solid footing as it has appeared since he signed there. Although he didn't really fully explain why, I think he expected Cam to come in and take all of the first team reps (or the huge majority) as the unquestioned starter and that clearly is not how they have been working it. He seems to think that Cam would just waltz in at take over the offense and they would have treated him stature wise like Brady.
Like I said many times over the last few weeks, there will be a million and one reports and hot takes on this one. I don't know how things will turn out, but if Cam looks like a deer in the headlights on some plays a couple of days before the season starts, he may not be the starter on Week 1 (which is not to say he won't take over as the starter . . . only that they are not going to send him out there if he is confused and doesn't know enough of the playbook).
