Over the years I have heard and read that Mac was the reason Borg retired. I don't believe he was the sole reason, but I do think after Mac took his #1 ranking Borg just stopped wanting to be #1. Maybe he felt it was too much work? I realize the guy was already a 10 year veteran on the circuit, but pro's back then seemed to have an "off season" of sorts. Many skipped the Aussie open. Some think Mac had nothing to do with it..... So what are your thoughts?
