I'm a big fan of Demarcus Cousins, but since we're playing hypotheticals,
If the C's traded Rondo (Bradley too?) for Cousins, Thomas, and McLemore, are we looking at an improved Celtics team or just another version of the Kings? I guess it would be good having Sullinger play PF in that lineup, and maybe the C's could have drafted a PG like Exum, Smart, or (more likely) Ennis to move Thomas to a much more suited 6th-man role.
But is that team actually competing anytime soon? I guess a foundation of McLemore, Sullinger, Cousins, and the 2014 pick have all the potential in the world, but I see the C's hovering around mediocrity a la early 2000s Celtics. Maybe one of those players morphs into a superstar, or maybe the team turns into the 2004 Pistons. I just see a lot of "very good, not great" though.
That's just me. I'm not even saying keeping Rondo will otherwise make the C's great in a couple years.
