In my opinion, I think Rondo is a better option. The Rockets has so many shooter already like Harden, Parsons (might be traded to Celtics for Rondo, hopefully not since he's the glue of the team). We also have rookies that can be trained and improved like the RGV's Troy Daniels (I sincerely hope he wouldn't be a defensive juggernaut like Harden), Isaiah Canaan (could be a third stringer PG) and Covington as back-up SF. With Rondo, he COULD and MIGHT change the defensive culture of the team. I mean we all know that defense is the team's slight? weakness.
