What is Lamar worth?

I lost out on Lamar Jackson due to waiver priority and have Cam Newton who I am worried about.

The owner of Lamar is both RB and TE needy and with Lamar having one good game and kind of an unknown I was wondering about offering up this trade.

Devin Singleterry + Delanie Walker for Lamar Jackson.

I could also try to swap out one of those two for Cam to see if it makes it more interesting. Does this seem like a viable trade offer or am I way off base?
