Top 20, sure, when he's on his game (he's proven to be very inconsistent).
Top 5? Take a break from the Koolaid, son.
No kool aid, only the fine vintage wine that is Rajon Rondo.
Lebron
Durant
Wade
Howard
Rose
Paul
Dirk
Kobe
Melo
Amare
Love
Griffin
D-Will
Westbrook
Ginobili
Z-Randolph
Bynum
That's 17 players right there that I think many people would consider better than Rondo and whose teams would not trade straight up for Rondo. I'm sure at least a couple more could arguably be placed in that category, too.
The struck through names are players that I'm not convinced are certainly better nor worse than Rondo. I've stated a few times on this blog that I find Westbrook to be definitely better, but Rondo has shown a lot early in the season and my opinion is swaying.
Other players to join those bottom 4 I would say are: Aldridge, Joe Johnson, Iguodala, Nash, Pierce, Pau.
Which means I can't say for certainty he's even top 20. Probably, but not definitely. If he plays with the intensity and heart we've seen and can do that consistently, then I'd put him around #10 or 11
Nash last year I would argue had a better overall season than Rondo.
I think Aldridge and Iggy are certainly arguable.
I forgot about Pau; I agree, I think many people would consider him a better overall player than Rondo. Pierce is debatable as well.
I'm not a big fan of Joe Johnson. I think he's solidly behind Rondo in overall worth. Joe Johnson is an overrated and overpaid player imo.
But yeah, Rondo might not crack the top 20 on many experts' lists.
