No way. He only occasionally busted his ass elbow trying.
Fixed that for ya.
In all seriousness, while Rondo is my favorite player I'd have to say no to retiring his number. The comparisons to KG are interesting, but there are several things that make KG's number retirement an almost certainty, and Rondo's pretty much not:
1) KG bought in to what it was to be a Celtic from the moment he got here. He embraced the tradition and what it meant to be a Celtic, and we loved him more for that. Rondo never chose us, since we drafted him (in effect), and while he embodied the grit and toughness Boston sports fans come to expect from their stars, playing through injury without complaint, excuses or wheelchairs, he didn't give up anything to become a Celtic, it just fit him well.
2) KG developed close relationships with Celtic legends. The Bill Russell conversation is powerful, and you can't help but believe there is a deep bond there, and it really ties him to the organization. Rondo mostly got lectures from Tommy, though I think if Larry were here instead of Danny, that may have changed a bit.
3) Coming to Boston, we helped KG do something he couldn't have done otherwise. Yes, he could go to a contender next year and win, but that would be more of a coattails championship rather than something he earned. Here, we helped put him in a position to earn it, and he did. While Rondo won a championship, too, he could very well go on to be as successful elsewhere for as long or longer.
KG and Rondo had very complementary careers in Boston, even down to their cap hits, as Rondo became a star as KG's waned. KG gets more credit for his time here because his teams won. If we won in 11-12, or even 09-10, rather than 07-08 I think Rondo gets more appreciation, as he took on more of the leadership and playmaking as he grew up. I also don't think one chose to leave the C's more than the other; Rondo probably would have left in the summer if Danny didn't pull off something miraculous again, and KG did waive his no trade clause to go to a supposed contender with PP. Neither of these were their first choices, but they did both leave, with an unknown but I'm guessing about the same amount of volition.
Ultimately while I wouldn't be upset or surprised if KG didn't get his number retired I do expect it to be, while Rondo, if he has the logical continuation of his career, shouldn't have his retired (unless we're still in the dumps 10 years from now and need something to make us feel better, of course).
