To me improving our scouting and drafting is the biggest thing they need to do. I'm not a big fan of Loomis right now, but I think he can change, stop trading up all the time, occasionally trade down, and stop kicking the can until we are a contender again. I'll be happy if he is no longer the GM, but I can live with it if he stays and adjusts the way he has been doing things. (Which he mostly has for the last 2 years.)
On the other hand, we have to improve the scouting and player evaluation. And that likely means Ireland an Parenton need to go along with bringing in new scouts.
It would also really help if our new head coach has an eye for talent.
