I'd keep all three wide receivers. Goff is good, but he should be around for a little while in the draft if you want him bad enough.
This way you can go rb/rb (Freeman is okay, but he would be ideal for your third rb) or possibly rb/te if you have any interest in Gronk or Kelce. You won't have to worry about WR. You've already got three who are capable of putting up WR1 numbers.
