I'm probably going to stir up a storm, but oh well. Powerlifting can be great, but it should not be a catch all program. Lifting, without running and plyo's etc., does nothing for an athlete. If that were the case then why was Arnold Schwarzenager and some of the other strong men not in the NBA, NFL, NHL, etc? Because they are strong, but not athletic. HUGE DIFFERENCE!!!!
Some of you are making the case that it builds confidence, self-value, etc. So do other individual sports. These all work the same way as powerlifting. Might make you faster or quicker (track), better footwork (wrestling) but this doesn't automatically make you a great athlete. Again, then why aren't all olympians in professional team sports. They can run! That's not an automatic qualifier for being a great football player.
This said I like powerlifting. I think it has its place. But too much bulk and no running is bad. Better for 11 man than 6. Kids that can run but aren't strong aren't ideal either. You must strike a balance somewhere. Any sport, if done right, can help in other sports.
Personally I think that a lifting program incorporating strength lifts, plyometrics, agility drills, and running are much superior to any individual sport. Just my opinon.
