If he were to retire today, ABSOLUTELY NOT. In the history of the game, very few 27-year-olds could claim they were already locks for the HOF.
Rondo has not done enough in his seven seasons to warrant inclusion in a group that includes only 150 or so of the best players in the history of the sport (many of them from the international/women's/college game).
Things working against him:
- He is not considered the top PG in the league, and there is argument to him not being a top-5 PG in the league. I know Boston fans will say otherwise, but Boston fans don't vote for the HOF.
- He has never been considered the leader of his team for a full season. This was supposed to be his first season as team leader, and it didn't start well, and ended with him injured.
- He has never finished in the top-8 in the MVP vote.
- He has only one championship, and was not one of the top-3 players on that team.
Things working for him:
- He has one championship (but so do a lot of role players; Mario Chalmers is about to have two).
- He has four All Star appearances, and though I think these shouldn't count because they're more a popularity contest than talent contest, Rondo should add a few more to his belt before retiring.
- He has made two first-team (and two second-team) All Defensive teams.
- He led the league in assists twice.
- He led the league in steals once.
However, Rondo's remaining career is all dependent on the Celtics staying in contention. Who knows what kind of player Rondo will be on a lottery team or how he'll mesh with a new team if he's traded at some point. Remember, he's played his whole career as second fiddle to a bunch of Hall of Famers. He has many years left in this league and he has a lot to prove if he wants to be considered a Hall of Famer. Look at all the work KG and Pierce have done over their loooooong careers, and Pierce was barely considered a Hall of Famer until the past few seasons.
Look how long it took Dennis Johnson to get into the HOF. Look at how Reggie Miller was passed over, and he was the all-time leader in 3-pts at the time. Mark Jackson is third all-time in career assists, and can't even sniff the HOF.
By the way, Basketball Reference has an interesting little Hall of Fame Probability Meter for active players, and Rondo currently sits at #26. That sounds great, except look at some of the names in front of him - Billups, Arenas, McGrady, Stoudemire... and the player directly behind him is Joe Johnson.
