BTW, my position on what I would have done with Philly, is also the same thing I was advocating Boston do way back in 2012 i.e. trade Rondo rather then enter a period of mediocrity and start over (here is a thread where I was advocating that in April 2012
http://forums.celticsblog.com/index.php?topic=55509.0).
To be fair, I'd been advocating the trading of Rondo for awhile at that point, but 2012 was my real breaking point on him because I saw that as Boston's last chance at contending (the core was just too old). Also, at that time I thought KG and Allen were going to leave in free agency that summer and I thought Pierce "might" retire. Obviously KG came back and PP didn't retire, though Allen did leave, though Boston was never a contender after that with that core because those guys were just too old and you clearly couldn't build a contending level team around Rondo. (and for the record I'm certainly glad KG came back and PP didn't retire, because that led to the Nets trade, which was awesome).
I saw Rondo in much the same way Philly saw Jrue Holiday in 2013 i.e. a good solid, even sometimes all star level player, but not a guy you could build a true championship team around. He was however still a guy that would lead to enough victories that your team would never truly bottom out (which as has been posted a lot, you need to bottom out to significantly increase your chances of landing a franchise altering talent).
