If the Cavs beat the Warriors in the NBA Finals, it won't be LeBron's greatest career achievement.
It may not even be second. (2nd being what he did last year vs GSW)
Certainly if LeBron helps topple a team that was loaded prior to signing arguably the 2nd best player in the NBA, it would be wildly impressive. But his greatest achievement? No. Here's why:
In 2007, just 4 years into LeBron's career, he dragged the Cavaliers to 50 regular season wins and all the way to the #2 seed in the East. He then led this team through round one vs Washington, sweeping the series. Now, before we continue, it's important to note who was on this team:
Larry Hughes, Donyell Marshall, Drew Gooden, Zydrunas Ilgauskas, and Eric Snow..Just to name a few.
Not exactly the who's who of NBA greatness. Anyway, he then led this team past New Jersey, and on their way to Detroit. Detroit, still comprised of former NBA champions like Chauncey Billups, Ben Wallace, Rasheed Wallace, Tayshaun Prince, and Rip Hamilton. LeBron led his sorry squad not only through them, they won the series in 6. And, the most impressive of all was this game 5 performance, to this day, one of the greatest performances in NBA history.
LeBron James scored 29 of the last 30 points for the Cavs in their Game 5 win over the Pistons. Unreal.
So yeah, a series win vs the vaunted Golden State Warriors and their 4 All-Stars would be quite the accomplishment, but nothing compares to that 2007 playoff run, especially that Game 5 win exactly 10 years ago from today, where the Cavs took down the Pistons 109-107 in OT behind LeBron's 48 points. Nothing LBJ does going forward will ever top that.
