Shaq had a good career with the Lakers, Magic, Heat, and Cavs. He was a three-time NBA Finals MVP (2000, 2001, and 2002), three-time All-Star Game MVP (2004, co-MVP in 2000 and 2009), 15-time NBA All-Star, and three-time NBA All-Defensive player. He won three consecutive NBA championships (2000, 2001, 2002) and a fourth title with the Heat, and was named one of the 50 Greatest Players in NBA history.
But his basketball skills are slowing down, which showed last season with the Cavs. They wanted Shaq and LeBron James to take them to the Promised Land. As we know, things didn't work out.
The Celtics should have only given him a one-year deal. Boston needs more than "Shaq Daddy" to win a NBA Championship.
