Why are people worried about Odunze?

Can someone explain to me how top 10 DC, as well as being paired w QB1 in his draft class is a bad thing? I keep seeing people on here complain about the landing spot because it’s a busy wide receiver room, but really it’s borderline perfect for him. Keenan Allen is on a short contract who works extremely well out of the slot, while Odunze plays the opposite side of DJ. This preserves keenan’s health which has always been a concern for him and maximizes his time on the team. It’s unlikely that they extend him after this year and then that’s even more targets for Odunze. Not to mention Caleb and Odunze have already been working out together so the chemistry is there.

Edit: Most of these comments reek of redraft mentality and nobody gave a reason outside of not getting immediate production which is okay in dynasty.
