RB needy team

Originally drafted Bell #1 overall, traded him for Fournette after week 1 fearing Bells extended absence…that ended well. Currently I’m sitting on:
RB’s: Fournette, Alex Collins, Dion Lewis, James White, Philip Lindsay
WR’s: Hopkins, Devonte Adams, Robert Woods, Amari Cooper, Quincy Enunwa, Mike Williams
TE: Gronk, Vance McDonald

My question is, should I trade Gronk for say Marshawn Lynch? I’m 2-2 despite starting Fournette/Alex Collins and not getting much from the RB position. But Gronk hasn’t exactly been lighting the world on fire either and I seem to be winning despite his performances.
Alternatively should I package say Gronk and Adams for some higher tier RB? It’s unlikely that my league mates do a fair trade since they are very aware of my need. I think I might be able to get like Lynch/Sony Michel for Gronk, Adams and say Collins.

What do you guys think? Go for these trades or stand pat.

It’s 10 team 1/2 point ppr btw
