One of the NBA's greatest players of all time recently took a shot at the number of players in the league today who have a very low shooting percentage from the free throw line.

Rick Barry, who made a name for himself for his unconventional shooting technique, criticized the players who average less than 70 percent from the foul line. He called them out, via Jonathan Bradley of Fox Sports, for not figuring out how to shoot better from that distance and even went as far as calling them pathetic. The 73-year-old added that someone's personal pride shouldn't get in the way in wanting to be better at that aspect of the game.

“The bottom line is, they have an aversion to wanting to try the underhanded free throw,” Barry said. “I just don’t understand why you wouldn’t try anything to try to get better and I don’t think your personal pride should come into play.

“There’s stuff out there to help these guys if they would look for it and be willing to get better. It’s pathetic if you can’t shoot 70 percent from the free throw line.”

…“They have to figure out their way to do it. If they don’t want to do it my way, they should find my son Scooter, who has an unbelievable new technology in a shooting sleeve with sensors … in three sessions with DeAndre Jordan he had him shooting over 70 percent and he didn’t keep working at it. It’s amazing.”

Despite using the underhand or “granny style” technique, Barry averaged a very high clip from the free throw line, making 89.3 percent of his shots from that distance throughout his stellar 15-year professional career.

The former second overall pick of the 1965 NBA draft is hoping his strong words can serve as a wake up call to some of the players today to work harder on their free throw shooting. He understands its importance and knows that it will also serve as a good example to the younger players to also try and work out on all facets of their game to become complete players, which could help them if they plan to be in the NBA someday.
