07:24 AM ET 05.18 | When it comes to free throws, LeBron James is the Cal Ripken Jr. of basketball. "I think it has been documented that LeBron changes his technique every three games," Dwyane Wade joked on Friday. James isn't going to be calling legendary Miami Hurricane Rick Barry anytime soon to discuss the underhanded approach, but the NBA's four-time Most Valuable Player is certainly open to suggestions when it comes to shooting foul shots. His current mentor: Ray Allen, one of the game's best free-throw shooters with a career average of .894. (For the record, Barry shot .893. in the pros.) With the Heat in a holding pattern until it learns its next opponent, James has had plenty of downtime to work on his free throws, which are always of premium importance in the postseason. In recent days, James' preferred method of practicing free throws and, more importantly, recreating the type of pressure he might feel at the line during a playoff game, is a competition-style game against Allen. More often than not, Allen steps to the line in the Heat's practice gym and drains 10 free throws in a row. James says he just tries not to "look crazy."
