Coming into his first NBA season, Rajon Rondo knew nothing but success on the basketball court.
He was a McDonald's High School All-American at Oak Hill Academy, and he set the single-season record for steals at the University of Kentucky en route to becoming an SEC All-Freshman team selection.
After two seasons, he left Kentucky for the NBA and was selected 21st overall by the Boston Celtics in the 2006 NBA Draft.
In his first year as a pro, Rondo shot a measly 41.8 percent from the field and an awful 20.7 percent from beyond the arc.
He finished the season averaging 6.4 points and 3.8 assists per game. But the very next season, Rondo was the Celtics' starting point guard, guiding the team to its first championship in more than 20 years.
Rondo is now a four-time All-Star and a multi-time All-Defensive Team selection.
