The Los Angeles Lakers made a complete overhaul of their roster so far this offseason. The new additions bring in a lot of experience. The average age on the current roster is the highest in the NBA at 31 years old. LeBron James is also 36 years old. Marcellus Wiley explains why the Lakers' age is only a number and why it won't catch up to them: 'Their engine isn't 31, it's 28.'
