it's obvious that you have thought a great deal about the subject and are not at all defensive regarding differing opinions like others who feel the need to flex their credentials on the blog.
I guess the difference in our opinions stems from your conjecture (which you rightly acknowledge is theory (no disrespect)) vs what I was trying to highlight as peer reviewed evidence. maybe part of the disconnect is the difference in terminology used in our fields. as orthopaedic surgeons we refer to valgus as an increase in the tibiofemoral angle (or amount of knock-knee) not the rotation of one bone relative to the other.
Ashish Bedi (U-M orthopaedic surgeon) studied hip rotation contributing to ACL tears, and found an increased incidence of injury with restricted hip motion, but this was in relation to femoroacetabular impingement and differences in pivot landing (not how he injured his ACL). something that we have no reason to believe that Drake Johnson suffers.
Moreover, many of the in vitro tests of ACL failure study fatigue failure vs catastrophic failure which is the likely mode of failure in live human subjects.
In addition, as you note, there are differences between studies of passive stability vs dynamic stability and which better represents real-life events. In the end, both of our fields have their own ideas regarding why people tear their ACL. both of us are probably right (and wrong) to some degree)
Here are some recent orthopaedic reviews regarding risk factors for ACL tears...

I appreciate the mechanics discussion, and I don't want to be condescending, but there are a few well defined risk factors for ACL tears. These are implicated in an increased incidence of adolescent females tearing their ACL compared to their male counterparts. These scientifically validated reasons include diminished ratio of hamstrings strength to quad strength and anatomy of the intercondylar femoral notch in females (smaller than males). This is obviously not Drake's problem...
non-contact ACL-tears like Drake's are the norm and are more common in people who have had an ACL reconstructed previously, so not totally surprising....
People are different in now much rotation exists in their femur and tibia and how much their toes point out when they walk. (duck foot vs pigeon toed) that has never been shown to affect their likelihood of tearing their ACL
Long story short... Go on Drake. Keep up the good rehab and kill it this fall

4 month until the bone heals, 9-12 months until full recovery. Probably faster than recovering from an ACL
|3 years 31 weeks ago||actually type II error||
Forgive me, I'm studying for boards now...
Type I error is finding that different groups are different when they actually are not
Type II error is failure to reject the null hypothesis when the two outcomes actually are differrent
In this case, the null hypothesis would be that no abuse occurred
