(warning: freaking long rant oncoming)
There's a lot of things I'd address, but there isn't enough space (or threads) to put it. So... I'll put it all in here instead...
I'll start at the absolute top of the team: The owner. As long as Dan's the man, we can't expect the quota year in and year out. But as long as he's in charge, he'll at least be open to tinkering with the Cavs. And if this year ends on a poor note, I think he'll be open to blowing it up and try again... with OR without the king. Having the ability to spend money isn't ever a negative in this sport, except for the one spending it (lol).
Now the GM. I think Koby did okay given the circumstances. But that exactly was the problem: Being put in those circumstances to begin with. Not having a GM in early July probably lowered a lot of those chances for success. Gilbert has to make up his mind and not that happen again... but this is Gilbert we're talking about. Hope this off-season will bear some fruit. But after LeBron makes his decision first.
And the coach. Not really a fan of how it played out. Should Lue have kept going with all of the health issues going on? Did we really have a choice? Whatever. He brought us to the NBA Finals last year after winning it all the previous year. He deserved a second look because it will be on his resume the rest of his career. But that "lightning in a bottle" doesn't always work out and gets burnt out. We're seeing that happen now... Hope these last 2-3 games are worth something to us, and to Lue.
15th year or not. LeBron is still a superstar. Any chance we have to compete is based on his decision this summer. I get the feeling that anything goes this time around. He could easily choose another team with immeasurable promise (with young talent). He could go back to us if we could convince him of our backup plan. There's always a dark horse out there to pry him away, but I can't blame him on making any decision. The only thing I'm sure of is if we don't keep him, we need to blow it up and try again later. Kinda get visions of 2011 Cavs, you know?
Kevin Love might be our #2 at this point, but I don't know how much more of it I can take. Yes, he gets freak injuries out of his control, but I do see a lack of toughness. Even if he doesn't complain, you kinda get it with his body language. He's much better off as a #3 because he can play off of the 2 ball-dominant go-to stars and stick to being effective by going dark. Either get a proper #2 to fill in the Kyrie Irving-shaped gap or move Love and try again...
The rest of those guys haven't shown much. And I don't think it would matter if we decided to play Tristan or Osman or Zizic or whoever the hell we have. It's more of a team issue. I saw Korver giving 150% effort that last game on D and he still had to sit the remainder of the the fourth quarter because he couldn't hit anything worth shit. I get the feeling that Lue's trying to get guys like Green, Nance, and Clarkson a chance to break out of their shell and get on the right track for the rest of the playoffs. But it isn't working. Maybe some youth is needed to inject some life, but it's not that I don't see Osman and/or Zizic giving us valuable time... it's that the rest of the guys they're with can't do much the begin with to get those guys involved. Hell, Daniel Gibson needed to play 15+ games in his rookie playoff campaign before breaking out with a 31 point shooting spree in a Finals-clinching Game 6. Hell, Lue's running out of options because of guys not stepping up, but I don't think it's because he won't play rookies a-la Larry Brown (Olympics-version). It's just how limited we are as a team. Plus, the other skillsets we have from other guys just aren't able to be utilized if under this much pressure.
The difference from a team like this versus one from 2015 is not a talent gap. It's the mental makeup and toughness under a lot of pressure. But also LeBron is still in his 15th year now... I don't think it's by design. The best way to learn about oneself is to look in the mirror and see what's wrong with you.
I hope this team still has something left, but not sure what. At least we got 3 Finals appearances and 1 championship out of it. I'll never forget that experience for the rest of my life and what happened to get there.
