This is just my opinion, but Id pull the trigger. Your getting the #1 best fantasy player the past 2 years for a WR whos got a foot issue and hasnt been playing well and another guy who loses goaline touches to his backup. I think its a must trade. I would do what you could to try and get Ben tate too. He may be on the waivers since hes hurt. If you ever get Foster in any league, you MUST also get Ben Tate as a handcuff. Most important rule in fantasy right there. You are still a little weak at RB since Murrays hurt. Maybe pick up Beanie Wells of waivers since hes sposed to play 2 weeks from now.
