Should I trade Fitzgerald n Sheppard for Kelvin Benjamin. I just traded Cooper for Evans n my other WRs are Brandon Marshall, Diggs, Fuller?

Kelvin Benjamin is a power house WR to have on your team. Especially when it's obvious that it's cams favorite target. Larry Fitzgerald is also a number 1 receiver with a good quarterback making the throws. It's subjective. You have a pretty good lineup of wide receivers already that will consistently get you points if you play the right ones. It's a personal decision. I'm not too big on trading. Just know that whatever you do you will have consistent points from your WR posistiom each week.

No. You'd be better off working on an area of your team where you have a weakness. Your WRs are fine.
