Just read through this thread. If I am moving Rondo, it is for a big, since Bigs are always harder to get than smalls. I would not trade him for another point guard. I also would consider trading him for a high draft pick so that we could free up some cap space, but with him just returning from an acl injury I don't see someone giving up that for him.
Someone earlier mentioned Vasquez. People complain about Rondo dribbling the ball into the ground, Vasquez is like a less good version of Rondo in that respect. I still hate him from his Maryland days.
