Trying to Work a Trade - Looking for Your Advice

Footclan, I really need your help here!

I’m 0-2 in one of my leagues but I feel like I have a really good roster. The league has 8 teams and is a 0.5 PPR scoring format. Top down, here’s who I got:
QB - Wilson, Wentz, Dalton, Luck
RB - McCoy, Hunt, Cohen, Abdullah, DeMarco Murray
WR - Demaryius, Julio, D. Parker, Garcon, JJ Nelson
TE - Hunter Henry, Jimmy Graham

I’ve been in trade conversations with the guy at 2-0 and in first. He really like’s Devante Parker who I think will have a good year, too. However, I look at my other WRs I start to think “Hmm… I’d be fine without Parker I think” Here’s the rest of his roster:
QB - Big Ben, Siemian, Cousins, Watson
RB - Hyde, Gurley, Gordon, Doug Martin, Derrick Henry
WR - Antonio Brown, Devante Adams, TY Hilton, Corey Davis, Terrelle Pryor
TE - Rudolph, Eifert

Here’s my questions:

  1. Would you trade Devante Parker straight up for Derrick Henry? That way I’d lock up the Tennessee backfield regardless of what happens to DeMarco this year.
  2. What would you offer him to try to get both Devante and Doug Martin? With Hyde, Gurley, and Gordon on his roster he’ll hardly have the opportunity to start Martin so I’d like to find a way to pry Martin away.

Thank you!
