His seven-year tenure was unforgettable to say the least.
But as we all know, the Akron native left Cavs fans in shock and disbelief as he announced he would take his talents to South Beach in the summer of 2010 to play for the Miami Heat. This move instantly changed the franchise's status around the league from title contender to laughing stock.
And with that, the future of wine and gold basketball became more promising than ever before.
Irving was sensational in his sole season with the club, posting averages of 18.5 points, 5.4 assists and 3.7 boards per game while shooting 46.9 percent from the floor and just a hair below 40 percent from three-point distance. He was eventually named Kia Rookie of the Year.
There's no need to say, however, that there's a large talent disparity between the two former No. 1 picks. After all, it's hard to compare anyone to arguably the best talent in the history of the game, let alone a 6'3" average athlete with only one year of professional experience.
Regardless, the Cavs will have a chance to be an even better team with Irving at the helm instead of LeBron.
