The guy only cares about profits and that is something he is good at generating for himself.
Unfortunately, this team is getting harder and harder to care about.
My initial instinct was to say he isn't very smart, but looking at your list, overall, he has made some good decisions.
It is very possible he would have done a better job with the bullpen if Arte would have let him spend money on it.
You only trade Adell for a front of the rotation pitcher with years of club control.
That isn't going to happen.
So keep Adell.
Trout, Marsh and Adell is an OF worth having.
