The Mount Rushmore of coaching legends finally has its fourth member – Sir Alex Ferguson.  Alongside, say, Vince Lombardi, John Wooden and Scotty Bowman, Ferguson will be remembered as one of the most successful managers of all-time and certainly at the top of the football/soccer ranks.  With his slightly surprising retirement earlier this year, he left behind a Manchester United club that is now valued at $2.3 billion thanks in large part to the 13 English league titles and 25 additional titles won in his 26 years at Old Trafford.
