It's funny because I was just joking about the Rondo for Rubio/Love thing, but now that I think about it, it makes sense at least on some level.
But regardless, my point was that Rondo is not locked in to this job. Once the Big 3 are gone, Danny may need to get creative to rebuild this team, and part of that could involve moving Rondo, opening up the spot for Rubio.
Obviously, it is way too premature to speculate on actual deals, but to rule out the possibility of Rondo being gone in a few years is also very premature IMO.
