The OP said "barring injury".
I don't think you can say "barring injury" considering Rondo's style of play. He's relentless and reckless, and while I love him for that I don't see it as sustainable. He's on the floor a lot and takes serious contact. If he weren't elastic, I think he might've had a few season enders already. Elastic gets brittle over time.
But I wouldn't put it past him to break Stockon's assist record by a large margin and put himself in the hall regardless of what happens.
He's not breaking Stockton's record, and neither is anybody else in the league right now. It's going to take a special, special passer - a "volume assist" guy as it were - with insane durability in a perfect situation to beat Stockton. Rondo's at best one of those.
But I'd be shocked if he didn't retire in the top 10 in all-time assists (again, barring serious injury). He's already almost halfway there. Depending on how guys like Paul, LeBron, and Deron do, I'd expect him to be anywhere from the 6th to the 10th player to crack 10k assists. Could very well finish somewhere in the top 5. He's got a shot at the top 10 in steals as well.
And I know it was a throwaway comment, but I'm surprised more people didn't respond to saying Doc would be a HOF coach down the road.
