With Ray on the court our offense slows to a crawl. That much is true.
Yes, cuz our offense was flying in 1st half before AB got hurt

I saw a guy with high basketball IQ noticing that ATL is essentially playing with 13 guards, and doing most of his damage in the paint on the cuts, which is ever weirder when you know that his job description is essentially to shoot, not to go to the hole in the last few years.
Ray Allen effect furthermore gave loads of open looks from beyond the arc to rest of our guys which is why we hit decent enough percent from 3pt land tonight.
I call it half double (team). Ray runs off screen(s) his man is on his heels but big is stepping up half way too, and Hawks entire D does the same half step to rotate in between (really fine job doing that), which gives our weak side spot shooter enough room to get the ball and shoot uncotested (MP did it good tonight). People that don't understand how basketball works can not see that he is the one getting MP open on those shoots eventhough he wasn't anywhere near the ball.
I have watched Ray losing step after step since his Bucks years, then transforming to more of an outside threat during his prime in Sonics, and then making ENORMOUS sacriffice with his game when he was asked to fit into C's system that he willingly made.
IHMO he is top 10 SG in league still, but more importantly he is perfect SG for these C's who need his spacing and outside touch and in return make him look like a decent defensive SG with rotations. Its a long shot, but I hope he will stay here after this season, specially since it seems PP is linking his retirement to what KG and Ray do in postseason.

shooting against "6ft Fisher who can stop him" in Seattle days (shift from his Bucks days noticable, over 70% of off career high coming from outside shots, eventhough he still kept hight FTA ratio) :
