Al Horford hasn't always been good at everything.
As a 33-year-old with 12 seasons of NBA experience and five All-Star appearances, Horford is skilled in most aspects of the game. Interior defense? He's excellent at it and was named to the NBA All-Defensive Second Team in 2017-18. Passing? The big man averaged 4.6 assists per game in his three seasons with the Celtics. Setting good screens, marshalling the defense and generally making smart, winning plays? It's his trademark.

But it took a while before Horford added outside shooting to his long list of tools. Looking back at the early history of Horford's career, his stats give you no indication that he'd eventually be a "stretch five" type of player, someone who's shot 37.1 percent from three-point range on 927 attempts over the last four years.
He made no three-point shots in his three college seasons at Florida and was 0 for 6 from long range in his first two NBA seasons. Horford was named to his first All-Star Game in 2009-10, a season in which he made his one and only three-point shot, and he hit 9 of 22 over the next four years. He took a small step forward in 2014-15 for the 60-win Atlanta Hawks, converting 11 of 36 threes.
It wasn't until the 2015-16 season, at 29 years old, when Horford started to let it fly with regularity, attempting 256 threes - 220 more than the season prior - and making 88.
Ben Simmons, like Horford, had no three-point makes in his first two professional seasons. According to Tobias Harris - a player who also has improved remarkably as a shooter over his career - Simmons was knocking them down from the perimeter during a recent workout in Los Angeles.
… He's in the gym religiously every day - grinding, getting better," Harris said at a press conference Friday. "He's in great shape. Everyone was trying to figure out why I was guarding him at the three-point line. It was really because he hit two of them. I dared him to hit two of them and he hit two in a row - that's why I was there. He's made big improvements on his game. His jump shot is looking really good. He has confidence to shoot it. I just kept telling him there, even in these workouts when you're playing, have the confidence to shoot them and don't get discouraged when you miss …
The Sixers have committed $170 million to Simmons over the next five years in spite of his lack of a reliable shot and because, as was the case with Horford, he didn't need one to be a deserving All-Star. Horford's development as a jump shooter is unique, but it helps provide context for Simmons' situation.
Perhaps the most important takeaway is that there's no shared path - jump shots don't all evolve at the same pace. Improvement is contingent on factors like fixing flawed form, natural touch and, as Harris alluded to, the confidence to take jumpers in games and the go-ahead to do so from teammates and coaches.
It's also not blindly optimistic to review Horford's past, consider Simmons' future and conclude that the 22-year-old All-Star is likely only going to get better as a shooter. After hitting 25 of 99 shots from 10 feet and out last season (25.3 percent), it would be very surprising to see Simmons regress.
It would be stunning if Simmons followed Horford's trajectory, too. You'd imagine his form will have to undergo significant remediation before he's a good three-point shooter - players with flared elbows and inconsistent mechanics don't typically fit that description.
However, two seasons is far too small of a sample size to judge Simmons' shot a lost cause.
As we noted on the night he agreed to join the Sixers, Horford shared that same opinion a little over a year ago.
"He's already difficult to guard," Horford told NBC Sports Philadelphia during the Sixers' 2018 playoff series against the Celtics. "Like all players, we all make progressions. When I came in the league, I wasn't shooting much outside the paint. And over the years, I've expanded my game - you can say that about a lot of guys. And I feel like with him, it'll just be another weapon in his arsenal, that he will continue to develop that [jumper]."
His perspective is one worth listening to.
