Made several moves to make my team competitive, should I make one more?

It’s a .5 PPR, 10 team league.

I just traded Gronk for D. Cook and it processes tomorrow.

My team now sits at 2-6 but should be 3-6 after tonight.

The trade I’m thinking is either Landry, Zeke for Hunt or Landry, Zeke, Sutton, for Duke Johnson and Hunt.

Here is my roster:

Kamara, Zeke, Cook, Murray
OBJ, Keenan, Landry, Marvin Jones, and Sutton
