PHILADELPHIA—Following yet another season-ending knee surgery, Philadelphia 76ers center Andrew Bynum openly wondered Sunday if he will ever have the chance to completely waste his talent on a basketball court again. “I’m beginning to worry that, with all these injuries, I won’t be able to get back out there and completely squander all of my abilities,” said Bynum, admitting that his chronic knee issues could potentially prevent him from ever fully underutilizing his God-given athletic gifts. “It’s just frustrating because I know that if I’m healthy I can definitely live up to one-tenth of my potential. I just have to be patient and diligent with my rehab so I can one day throw away another opportunity to become the best center in the league.” Reached for comment, Bynum’s orthopedic surgeon Dr. David Altchek told reporters he is confident Bynum will recover in time to fritter away his wealth of natural talent at the start of next season.
