1. Agree, Nagy being gone is probably the single biggest positive on the offense. Even with Nagy and Fields, they were finding ways to move the ball. Now as an offense, can they find ways to score TDs?
2. I don't think anything has changed. Mooney is a solid receiver in that high WR2, low WR1 area. He is a young, ascending player. Now the questions are: Can he be consistent? Can he be that reliable guy that gets open, makes the tough catch, game in and game out?
3. I agree. I think people have been too hard on Kmet. He isn't a move TE. That doesn't mean he is a bad TE or that he cannot positively impact the offense with both his pass catching and his blocking. It just means he's never going to be Kelce.
4. Too early to know what we have in Jenkins and Borom and also whether or not they can stay healthy. They both have a chance to be good. But, they need to stay healthy and execute. Only time will tell and there isn't much depth behind them.
5. David Montgomery is solid RB. Both he and Herbert make a good RB room.
6. I fully expect Pringle to be able to contribute to the offense. But last year was his first year with more than 500 yards receiving and that was with Mahomes. He is right in the WR2/3 category. You need guys like him, but you need more than 1.
All QB's need a bit of help. They can't block the defense and they can't pass it to themselves. So, like any QB, Justin needs time to throw and targets that run good routes and can be in place, on time. Then, it's up to Justin to make the right read and the right throw, on target, on time. He can help the offense out by not holding on to the ball too long, being decisive, and then obviously making good throws. He has a great deep ball, but he is going to have to learn how and when to take his shots while keeping the offense moving.
As far as Fields' athletism, he has always struck me as a passer than can run, not a runner that can pass. In college, he could hold on the ball and hang out letting really long plays develop both due to the line in front of him but also because he was just about the most athletic guy on the field - he could pretty much always escape. In the NFL, there just isn't that much margin, and they are stronger so it's not as easy to break a tackle. He can do it, but not as easily or consistently. And quite honestly, while he is tough, you don't want him to take a lot of extra hits either. So yeah, he can make plays with his feet and throwing on the run that other guys generally cannot really do, or at least not as often/easily. That doesn't mean you always want him running for his life after holding the ball hoping someone, somewhere finds a way to actually get open.
