realistically if you're building a team from scratch right now you'd take the following players over Rondo.
Bron
Dwight
Durant
Kevin Love
Blake Griffin
Chris Paul
Deron Williams
Rose
Kinda no-brainers there.
You have to take Wade over him too, right? Another no-brainer.
Tough call whether to take Rondo or Westbrook.
And beyond that I really can't fault anyone for taking guys still on their rookie deals to build around such as Steph Curry, Kyrie Irving, DeMarcus Cousins, Rubio... I'd trade Rondo right now for Curry or Irving without question. You could probably talk me into Cousins or Rubio just based on their potential and contracts.
Also can't fault anyone who would try to win in the short window with a guy like Kobe or Dirk. Think of it this way... if you're starting a franchise from scratch and need to grab a guy... who has more trade value? Kobe or Rondo? You'd have to take Kobe even if you didn't plan on keeping Kobe.
Also can't fault anyone who would rather start building by grabbing a big... so that means Bynum, Pau and Bosh are all defensible.
I mean, really... the case could be made that taking Greg Monroe over Rondo would be better since Monroe is a 6'11, 250 pound PF/C who is 21 years old, averaging 16 points, 10 rebounds and makes under 5.5 million until 2015. I'd have to think real hard about taking Greg Monroe over Rondo if I'm grabbing a guy to build a team from scratch. Why take on Rondo's 12 mil if I can take on Greg Monroe making 3.3 mil next year... give myself some cap room to find pieces to fit around my star big man. I mean, really... if Detroit offered us Greg Monroe right now straight up for Rondo (and could swallow Rondo's salary), wouldn't we have to do it? We'd have to, right? Based entirely on the logic that having a 21 year old big man on his rookie deal is better to build around than a 26 year old PG making 12 mil. So that kinda answers it.
So by my count... Rondo is arguably #21
