I thought UR did a good job defending Green. Made it difficult for him, and that was well done.
But, when someone says X, Y, or Z stopped or held a GREAT offensive player to 0 points (or whatever), I disagree. A GREAT offensive player (I'm not saying Greene is, I don't know) can score on anybody. There is no defense that can "stop" the offense of a great scorer. Above average defenders can sometimes slow a great offensive player down, and make it more difficult, but defense is not capable of stopping a great scorer for an entire game.
When great shooters get in rhythm they are virtually unstoppable. A quick look at the film posted earlier in this thread makes me suspect that Greene is a well above average shooter. He was coming off screens firing threes, falling away from 3, hitting with defenders in his face (and all over him), and scoring from everywhere with all kinds of shots when he was putting up 30, 35, etc. The attempt at defense had little to no effect on his scoring. The shots that Greene was making in his big scoring games support my point.
The opposite is also true. When a shooter can't get tuned in, (flip the switch for whatever reason) they suddenly become very controllable. Sometimes a great shooter can't hit the ocean from the deck of a cruise ship. When that shooter can't get their rhythm, confidence dips, and they are a different player.
I'm not saying that the Spiders didn't do a good job on Greene (read statement # 1 above again). The defense impacted him, which is good, but his rhythm and mindset kept his scoring from going off. If his switch had been flipped on, he would have put up big numbers today just like he did in the other games.
Understand that the point of this post isn't referring to the average player. Defense CAN often control an average or below average offensive player. But, the average player doesn't put up multiple games of 30+ either.
