LeBron didn't have to wait, as Love wasn't a must. He wasn't even a good fit for the Cavs, as became evident now (IMHO). Other star vets in FA may have been just as ready to form a "big 3" of some sort.
Wiggins, on the other hand, could have been a star in the making apprentice/ future franchise player (with Kyrie). Someone who could gradually take the burden of leadership, and sustain the team's success for years to come, like SAS manages to do so well.
This is the sort of extreme "win now" mode that Bron forced the Cavs into, noted also in their failure to stick with David Blatt, a great BBall mind that you could try and build a dynasty with, but not an NBA-proven HC.
I really think that this Bron-induced state of mind will backfire big time, leaving the Cavs depleted of talent and title-hungry for at least another decade. Well, only time will tell... (not long, really. I think this post-season marks the close of this super-tight window of opportunity).
Back to our beloved Kings, and what we can learn from it -
I really hope that we don't overdo our own "win-now" attempt.
I think we should build around local heros and locally developed talent, like the DMC/WCS pair, with the likes of Omri Quincy & Seth. (Sorry if I missed some).
All these are hard working players that either call Sactown home, or feel gratefull to this team for their chance to shine. That is the core to build around and carefully add picks and FA talent into, as I see it.
That humble core, with the right young, hungry, up-and-coming, great coach (Walton? Blatt?) and some patience and stability upstairs WOULD TURN THIS ORGANISATION AROUND.
One year of THAT, even if we don't make the playoffs (and I am sure we WILL) - and Cousins would NOT want to go anywhere! (Good things feel good even in the making)
