Should I trade away Lindsay, Howard and Chubb for Fournette and Cook?

The rest of my team is AJ, Hopkins, Allen Robinson, Bell, Murray, Clement, McCoy, Foreman. It’s a 12-team half PPR league and the format is 2WR, 2RB and 1FLEX. My current record is 4-3 and I should most definitely be making the playoffs.

I’m also trying to have to guy trade me Conner but it’s less likely to happen. If I can get Cook and Fournette then I’ll secure Viking’s backfield and have Bell and Founette to fill the other RB spot and the FLEX spot.

What do you guys think?
