I know this is the current narrative but what you said flies in the face of what happened on the court.
1. Yes we need to play faster but we were playing SLOWER before James took over the point guard duties. We were playing at about 87-88 possessions per game through the Utah game, either the slowest pace in the league at time or second slowest.
2. "When they looked bad it's when James held on to the ball too long."
Yes, he did hold onto the ball often, but we also had the 4th best offense in the league through 30 games, better than the beautiful ball movement offenses of Golden State, San Antonio, and Atlanta. If we accept that nobody hurt the movement on offense more than James then we are saying other than James's ball stopping, the offense was the best in the league because as it is, we were fourth with all that ball stopping. Is that likely? The fact is that James created a lot of the offense that led to the number 4 offense. He hasn't been perfect and he has played below his lofty standards but he was a big part of why the offense was good in the first place and the only reason we have a winning record because the defense is awful. I really don't see how the biggest issue someone can have with this team is how we ran the offense when our offense was 4th in the league and the defense is bottom 5.
A big on defense and some athleticism will help and I'm sure complete buy in from everyone will help, too, but we have statistics about what happened on court which refute a lot of what people are saying.
With bad said, I like Blatt and feel he will be successful sooner or later.
Again, I agree with the majority of your post, but I think two things need to be pointed out. We are dealing with fairly small sample sizes, especially the sample size of games before Lebron took over the facilitator role, which I agree has been a net positive in the short term, but if it kills ball movement and undermines the coaches scheme, I think it could be a net negative long term.
Secondly, I would argue that much of the really bad losses, which have killed moral as of late, have been because Lebron was lagging on defense, AND holding the ball. Sure, hes a huge net positive, but if we're talking about building team cohesion and building trust in the coach and overall philosophy, he has NOT helped Blatt's cause very much. And that's especially in regards to the defense. (of which I still think Posey, Lue, and Drew should be mostly accountable for early on)
It was obvious that Lebron pushed for them to use the old hard show, trapping defense that he used in Miami early in the year, and it was also obvious the Cavs do not have even close to the kind of athletic roster needed for that kind of scheme.
My point is that, when you think of the greater picture, Blatt has really had his hands tied in many ways from the beginning. If Lebron has such a "genius" basketball mind, he wouldn't be continually playing uncreative basketball, implementing schemes that don't fit the roster, and showing a lack of an eye for talent. (See: Joe Harris is going to be a big part of this team this year, Jawad Williams is great, Shabazz Napier is my guy, go Johnny Football, and on and on).
Everything trickles down from the top, and the top is Lebron. But it really should trickle down from the coach, especially when the star player isn't as smart as people are lead to believe.
