It takes a while for these guys to come back
Of course you are right and I totally agree. The problem is, for whatever reason, Gordon has never had his knee repaired. You bring up Bynum, who Gordon said has the same condition. What happened to him? He ended up eventually needing surgery..
"This ends a year-long saga that saw a seemingly routine summer procedure turn into a serious injury. Bynum had an Orthokine procedure in September and was expected to return for the start of the season, but his timetable kept getting pushed back. Questions persisted as we reached mid-November until the 76ers' center admitted he suffered a setback in his left knee due to a bowling accident. Bynum has occasionally practiced since then, but never seriously enough to return."
So we are all just waiting for the other shoe to drop, until Gordon takes it too far and finally has to have it properly repaired..
