JaVale McGee entered the league with a lot of expectations on his shoulders. People expected him to become a dominant big man thanks to his length and athletic traits and how he performed in high school and college.
But as you may know by now, he struggled mightily early in his career to establish himself as an impactful player, constantly being the butt of the joke and even starring in Shaqtin-A-Fool more often than not.
Nonetheless, McGee has definitely redeemed himself over the past 5 years or so. He's become a big factor on both ends of the floor as a rim-runner and a rim-protector, playing a big part in multiple championship teams.
