Giannis Antetokounmpo and the Milwaukee Bucks are heading to their summer vacations earlier than they would've liked. 

The up-and-coming Bucks are certainly on their way, with Giannis anchoring their team and making them one of the most formidable in the league. They were far from a pushover for the Toronto Raptors, but it's clear they aren't there just yet. 

Antetokounmpo can absolutely be the star that makes the Eastern Conference fear the deer, but the 22-year-old phenom still has growing to do - and we aren't talking about his 6'11 frame. There's one area he must improve on if he's going to be the real deal. 

Giannis can do just about everything on the court. He's a willing passer, an amazing defender, a thunderous dunker, an acrobatic finisher and a feared shot blocker. Antetokounmpo's biggest flaw is one that can't be overlooked, though. 

That issue is his perimeter shooting, especially from beyond the arc. He's a career 27.7 percent three-point shooter, and his lack of outside shooting was on full display in the final moments of the Bucks' season. 

Antetokounmpo had the ball in his hands down three in the NBA Playoffs with less than 10 seconds left in the fourth quarter. It's the kind of final possession situation that NBA superstars love, giving them a chance to rise above and hit the heroic shot.

Instead, Giannis dribbled along the top of the arc against the significantly-smaller Kyle Lowry before settling for a dunk. That left the Bucks down one with 3.5 seconds left, not nearly enough to intentionally foul and get a cleaner look than the one Antetokounmpo waved off. 

Here's how the Bucks' playoff run came to an end with Giannis not even attempting the overtime-forcing three:

Bucks head coach Jason Kidd pointed out the error after the game.

"Understanding he can’t wait, he’s got to go to score it, we’ve got to find a three, or he’s got to shoot a three. … He hasn’t been in that situation, so this is a lesson learned for him," Kidd said.

The good news for Bucks fans is Giannis knows his three-point shooting is a glaring problem and he plans on working on it over the summer.  

"The two specific things I want to work on this summer are getting stronger and being able to knock down open threes, open shots. That’s it," Giannis said following the Bucks' elimination. 

Add a three-pointer to Antetokounmpo's game and he might just become an unstoppable force as he continues his rise in the NBA.
