It's "you're" and not "your". I could find 3 videos on Lebron that would suggest he is a subpar defender as well, so your video examples aren't worth anything either.
Anyone can pull a metric out of their ass. Using that same metric, KO looks like a stud defender with a -3.0. Does anyone in their right mind think Kelly Olynyk is an elite defender? Reliance on a single statistic doesn't work very well when that statistic is rather suspect.
One very simple reason for this metric is that the team started playing better team defense once Rondo and Green were sent packing. Sully's injury (which occurred
after the team started turning things around) denied him the statistical benefit of the bulk of the team's improved play the last half of the season - the majority of that improvement being on the defensive. Some short-sighted, incorrect folks like to try to time the turnaround to Sully's injury, but it most directly equates to the trade of Green. The Cs played about .500 ball post Green until Sullinger went down.
Furthermore, Sully spent a fair number of minutes grossly out of position at Center last year. 3 of his top 7 rotations in minutes played had him at Center. He can't play there and doesn't belong there. His Net 48 is significantly worse there. That's just a poor use of him.
DRating and D +/- are not horrible for Sullinger. They're not good, but they're not that bad either. No one is saying that Sullinger is even an average defender. But "horrible"? Not even close.
This isn't necessarily directed at you C4Ever, but I find it amazing that there's fair contingent of people who are ready to give up on a guy who just turned 23 years old and is the team's most consistent rebounder and scorer. A guy who was averaging 16/9 the last 15 or so games before he got hurt at just 22 years old. Actually, I don't find it amazing. This is CelticsBlog after all and they'd find a way to nitpick Bill Russell if he were still playing.
So they make crap up and cherry pick statistics to try to show that he's a scrub and want to give him away for pennies on the dollar. Thank goodness these geniuses aren't running the team. Now is exactly when you don't sell Sullinger. His trade value isn't that high right now due to the injury. If he comes back to camp overweight again, it won't hurt his value to trade him at that point. But if he comes back to camp motivated and in shape - and it sounds like he realized this is something he needs to do - then you have something valuable. That's going to translate to better play on the court and the team will have a more valuable asset to either resign or trade to someone else.
Unless the offer is great Sully isn't getting moved this offseason. Danny NEVER talks down an asset before trading it.
