Lets not forget we live in a world where Omer Asik is making $9M, Wesley Matthews is making $16M, Chandler Parsons is making $15M, Tristan Thompson is making $14M, and Iman Shumpert is making $9M.
In today's NBA $7M for Evan Turner is the bargain of the century.
We also live in a world where you'd better be able to shoot the three if you're not a really excellent rebounder or slasher.
Funny you say that, because Turner is both an excellent rebounder and an excellent slasher.
For his career he's averaged just under 7 rebounds Per 36 minutes (excellent for a Small Forward) and his ability to 'slash' to the basket is a big reason why he's had such a positive impact on our team offensively.
Evan Turner's role in the modern league is to be a 6'7'' backup point guard. He's a more talented player than Crowder, but his skillset is less versatile and fungible because he doesn't have the same 3-and-D potential that Crowder has. Crowder could play on any team in the league and help them win. Turner needs to be somewhere that will give him the keys to the offense 20 minutes a night.
That is completely untrue.
Crowder had a Defensive RPM of -1.07 last year, and Turner's was -1.37, practically identical.
Crowder is great on-ball defender and a horrendous off-ball defender, while Turner is average at both.
In the end it pretty much evens out.
Also Crowder has been no less horrendous as a three point shooter than Turner has as a Celtic, so there's nothing there either.
Also to suggest Crowder is more versatile - wow. If there is one thing Crowder doesn't have it's versatility. The only thing he does productively is play good on-ball D, and rebound pretty well for his position. At everything else he is woefully mediocre at best.
Turner has the ability to play three positions
comfortably, he can score, he can rebound, he can pass, he can handle the ball, and he can defend. If a guy gets injured, he is a virtual swiss army knife due to his ability to fill in at such a variety of positions and roles.
Turner's versatility is the very reason why he was able to put up so many triple doubles last year. Crowder will probably never record a triple double in his life.
Turner also has (IMO) higher upside. He is basically only a three point shot away from being a "do everything" player, and if he developed that shot he could develop into pretty special player. Not an All-Star, but a very good starter. He also is more likely to develop that shot since he already has a good midrange jump shot, while Crowder really doesn't have a reliable jumper from anywhere.
Turner has the potential to be a 14 / 6 / 5 guy as a starter. If he developed a three point shot, he would easily have 17/6/5 potential. Crowder has the potential to be a 13/7/3 guy at best.
As I always say I really like Crowder, but Turner does far more for this team and is way more valuable. Just look at the +/- stats for this season. Turner (along with Olynyk) is pretty much leading the way. The impact he has on the court is huge for us.
