(Not a "Verboten" topic)
You'd think, with all the knee scoping and ACL and MCL surgeries, etc., that doctors know every little part of the human knee. Wrong.
Doctors in Belgium discovered the "anterolateral ligament," or ALL, which 97% of us have. If that rips, you get a "pivot" problem. Fixing an ACL doesn't solve this. They don't yet know how to fix an ALL, which, you know, makes sense, since they only just discovered it -- although it was first theorized by some doctor over 100 years ago.

And yes, it might just explain the problems on the O line this year.
