Drew Lock trade! (Dynasty)

Dynasty trade:
We already can draft NCAA player years before their original draft year:
I have Drew Lock and I’ve been offered Mike Williams straight up for him.
1QB,1RB,2WR,1TE & 1Flex
My team:
QB: Ryan, Jackson, Drew Lock.
RB: D.Cook, Freeman, Barber.
WR: Adams, Kenny G, Baldwin, DJax, K.Stills, Agolor.
TE: Henry, Brate.

Should I do it? I know I need a RB but I don’t know if I can pass on this offer.

Thanks for the help!

I’m dot a devy player, but invested in dynasty and therefore the declared rookies. I would def trade Lock away to receive Mike Williams in a 1 QB league.
