The play looked how it looked. Regardless, not all knee injuries require surgery. I wasn't adamant about anything except that the hit looked bad. I haven't downplayed anything. Go study sports medicine some and then come back to me.
That's why it's "similar" and not "the same." If the UAB defender hit him with the same force as that OSU defender then it might have been the same. But he didn't, which is why it "could be" "some ligament damage" and not a knee dislocation.
See the screen shot above, his foot was planted. Not that it means there is ligament damage, but with the foot planted the tibia can translate posteriorly against femur which increases the tensile forces on the ACL and PCL.
No one said it was as severe an injury. The mechanism of injury was the same, the force in McGahee's was way more which is why he had multiligament injury. And guaranteed he had bone contusions too. You get the contusion before the ligament fails.
You should watch the play again. Foot planted, hit the tibial tuberosity, hyperextension. I hope he’s good to go and it was just a contusion or sprain.
