Does anyone here have a problem keeping thier eyes on thier mark? I have always kept my eye on my mark when I throw, but lately I've found myself looking at the lane right in front of me when I release. I think I'm doing this because I'm sort of loosing the foul line. Anyway, This is very frustrating, and causes some inconsistency. My question is how can I get back to focusing on my mark and get comfortable again because now I'm kind of lost in between doing both. Please help!
