The 'limping' bit doesn't provide any information at all.
If you go and watch a lot of professional athletes - especially after they've been through a few years of bumps, bruises and injuries - in their everyday lives, off the court/field, you would see that a LOT of them limp when they walk and move at 'normal' speed.
Limps sometimes become habitual after an injury and may or may not have anything to do with health status. They may or may not have any impact at all on the athlete when in 'competitive motion'. Physical therapy often tries to correct for limps but it's harder to correct casual mechanics than deterministic ones. Thus, an athlete will often get his running, jumping & other decisive mechanics corrected sooner and more permanently than he/she will with more casual motion such as walking, which is often done without thinking too much about it.
I.E. - an athlete will know that he should walk without the limp, but catches himself doing it all the time.
I am not saying Rondo is ready to return any time soon. Thats up to Rondo and his doctors. I have no expectations about when he will be back.
But Danny's observation that he saw that Rondo still had a limp really isn't useful for drawing any conclusions about Rondo's return schedule.
