A lot of people have been conditioned to believe that rebuilding needs to follow the philosophy that you are bad, then suddenly become good.
That's not how good teams rebuild. Whether Drummond becomes a vital piece moving forwards, no one truly knows. What I do know is that fostering a culture of wanting to win games and driving players towards that goal is extremely important to young players. Give them something to aim for and create a culture of winning.
This should be a franchise that does everything it can to win games. Much like the Miami Heat, who never really bottomed out and now look like they could be an eastern conference contender for a long time. Get some players, see what happens and then move on from there.
Seeing what it cost the Cavaliers and the potential upside, I don't think I've seen the Cavs make a better move than this in a non-LeBron Cavs team since I've been alive.
