Big Trade Time - Non PPR

So I lost Barkley for the next month or so and I think I need to make a move in order to hang this season. Thoughts on this trade?

I Give:
R. Mostert
C. Kupp
M. Andrews (10th round keeper next year)
2020 3rd round pick

I Get:
N. Chubb
M. Gordon
C. Samuel
2020 12th round pick

The draft pick is the real kicker for me as I’m nervous to lose a 3rd round pick next year. With that being said, should I do this trade? Should I do it if I can make that 3rd a 5th?

My RB: S. Barkley / L. Fournette / C. Hyde / R. Mostert / J. Williams
My WR: A. Thielen / T. Lockett / C. Kupp / M. Hardman / D. Johnson
My TE: M. Andrews / D. Waller
