DMC has potential, not proven talent.
He is not a win-now player, he is a project player; high-risk high-reward.
I am not saying that getting Cousins would be a complete mistake, but the people both opposing and championing him seem to drastically misunderstand his game.
What Cousins is good at:
Rebounding (he is a beast on the boards)
Getting to the line (he is really good at drawing fouls, and because he is a decent free throw shooter he tends to generate points from this)
What Cousins is bad at:
Scoring (anyone who looks at his PPG is a fool who doesn't understand the game of basketball. PPG is MEANINGLESS without considering his FGA and FG%. All of his shooting splits are well below the league average, except FT%. He is NOT a good scorer.)
Defense (he gets a lot of steals, but not nearly enough blocks, and he fouls too much)
Passing (WAAAY too many turnovers)
Overall, he is a very inefficient player, and has been the past two seasons. All of his efficiency numbers are below the league average, which is bad. However, the devil is in two things: his shooting and turnovers. Even his defense isn't terrible, it just isn't good.
If DMC cuts down on his turnovers and improves his shot selection, he can be a great player. Definitely All-Star potential. The keyword, though, is POTENTIAL.
If you honestly think that plugging Cousins onto our roster as he is playing now will do anything but hurt us, I am sorry but you simply do not understand anything about the sport of basketball. The stats AND the eye test AND the general consensus of sports reporters agree on this point; Cousins has potential but isn't there yet.
Now, that leaves us with two scenarios:
Cousins comes to our team, refuses to improve, continues to be a head case, and we get nowhere.
Cousins comes to our team, changes his game/mindset (a la Blatche in Brooklyn this season), and we get an All-Star caliber big man.
So, as I said, this is high-risk, high-reward. This is not a win-now trade, this is not a safe trade. This would be a project. I just wish people would understand that. Thinking that it will be one extreme or the other as everyone who has posted in this thread seems to is foolish, and belies a complete misunderstanding of the way the sport works.
