Lunging is a great illustration for the slide.
Dave, yes. I think you hit the nail on the head. My PSO was telling me when he corrected my pitch that I slide, and stop for fear of going over the foul line, but even taking half a step back, it hasn't addressed the pressure on my knee. I actually thought it may have been weight related, so I lost 60 lbs over the last 12 weeks.....still knee issues.
I don't really think a Doc would be able to help Charlest, because I can imagine them telling me the only true way to stop, is to stop bowling, or change my entire game. I'll try and grab some shots @ league this week.
