This conversation about how you can't build around point guards is totally ridiculous.
Of course you can build around point guards; the caveat is that they actually have to be as good as you think they are, and you have to surround them with good enough pieces.
All "building around" somebody means is that you don't intend on getting a player that's better than them (because then, ipso facto, you would technically be building around the other player). So if you're building around point guards who aren't a top 10 talent in the NBA, you're pretty screwed unless you get lucky like the 2004 Pistons, since virtually all championship teams require a top 10, if not a top 5, player.
The problem is that most point guards aren't as awesome as people think they are (Derrick Rose, I'm looking at you). But you're freaking nuts if you don't think you can't win a championship with Chris Paul as the best player on your team, considering he's probably a top 5 player in the NBA.
In fact, there's actually a pretty huge dropoff after Chris Paul. Derrick Rose might be considered the 2nd best point guard after Paul, but ironically he's maybe the 20th best player in the NBA.
So what does that mean? It means that if you want to build around Derrick Rose you're probably screwed, but not simply because you're building around a point guard... rather because you're building around a player who's not a top 10 talent.
It's freakin simple logic, people.
So moving on to the facts of OUR case...
Rondo is a top 30 talent if you're lucky, therefore, the idea of building around him is flat-out insane. Unless we were somehow able to pull a Detroit Pistons and get the 31st, 32nd, 33rd, and 34th best players in the NBA as our other starters. And that never happens for a variety of salary reasons. The Pistons pulled it off by pure serendipity, and it just can't be replicated on purpose the way salaries work under the current CBA.
