Unproven Roster -Trade help

Hello,

Someone in my league needs some WR help and I kinda need RB help. This is my roster:

Rodgers
Henry
Moss
A.J Brown
Chark
Kelce
Slayton (flex)
Saints
Kicker

Bench
Jeudy
Pittman
Akers
Devante Parker
Mattison
Lock
Broncos (to be dropped)

The initial trade was Chark for Montgomery. But now he’s thinking of doing Chark + Akers for James Robinson + Montgomery (I was originally going to ask him for Conner until he got injured). He has Mixon and Jones as his RB. Sutton and Allen as his WR

Should I roll the dice with my unproven roster and stand pat or do this trade?

Thanks,
