Rose has been playing ball for months now and there is still no sign of his return. It's great for Rondo that he can at least be on the court, but I think we should all be happy if he is 100% by the start of next season.
Rondo partially tore his ACL with no other structural damage in the knee. Rose completely tore his ACL, his MCL, and if I'm not mistaken his PCL. Rose isn't a good indicator of how Rondo will do.
