Maybe, but the OL should have Smith at the peak of his skills if healthy and a still improving Frederick and Martin. Collins could be an upgrade at LG in his third year. Big ? at RT however. WRs all in their prime. Future HOFer at TE. Superstar RB in his second year. They could still be getting better as a unit.
I understand your points. I feel though Dez is not the force he once was and Witten is also nowhere near as productive.
Collins won't be a clear upgrade over Leary. Collins is more athletic but Leary's ability to anchor complemented the other linemen better, I think.
I'll feel a lot better if Green can fill Free's shoes and finally stay healthy.
We could use a shot of speed for sure, and I'm not saying that won't happen. We have a strong core for this and future drafts to build upon.
The biggest thing is Dak should keep improving. The Detroit game showed how dangerous he can be when given the opportunity. I choose to look upon that game as a sign of things to come.
