In your case I would see how he bites on Britt for VJax straight up, if not then tempt with throwing in Julio ...
Additional players come in handy when you offer a great handcuff to someone your oppnent may have ... ie the trade I just finalized yesterday
I gave Jahvid Best/Ben Tate
and I got Brandon Marshall
the ower I traded Best/Tate too had Arian Foster and S-Jax on his roster so he A) get's a better starter over S-Jax and B) get's his Foster handcuff.
and I come out with Marshall who solidified my WR corp.
RB-Rice, Mcfadden, Wells, Moreno
WR-Wallace, Marshall, Mike Williams (TB), MSW (Stl), Colston
LB-Matthews, D'Qwell Jackson, Von Miller
