I would prefer to be bringing in good midfielders but this year there is nothing to match the over all quality of the three proven players we can get in. 11 could land us a good midfielder via the draft but with the three trades we are bringing in proven players who all will improve us.
The obvious risk is what you have said and that is maybe missing the gun mid via the draft or trade next year. It is a risk but I think with the quality coming in it is worth that risk.
There is nothing we can do now that gives us another big body top line mid for next season. Who knows what next season will bring, someone may step up, someone may want to be trade out or the hail mary event Rory Sloane comes to us via FA

.
It is a risk, I agree that we need to improve the midfield but this year i think we need to run with the chance of bringing in 3 players who will make a difference.
