The Arizona Republic has a long article about the work Penny Hardaway has been doing to rehab his injured leg.  It details the problem he has where he can damage his leg and not be aware of it until it's bone on bone (ouch!).  At first, Penny couldn't even do a one leg hop over a coffee cup but now he's back to dunking.  Recently, he scored 43 points in a summer league contest.  That's a long way over a coffee cup jump.
