Avery and Moreno for Berrian and LJ?

[vsquared18]

My Team:
QB - Romo, Russell
RB - R. Brown, R. Rice, K. Moreno, Betts
WR - R. Moss, L. Moore, D. Avery, Chambers
TE - Miller, Celek
D/ST - GB, Denver
K - Tynes

It's a standard scoring non-ppr 16 team league with 2 RB and 2 WR no flex. I am getting Larry Johnson and Berrian for Avery and Moreno. I am really hesitant to trade all the upside but Avery out for a bit and Moreno in a crowded backfield I am starting to consider the trade?
