I think this was the link you were trying to post: https://bleacherreport.com/articles/10115893-video-11-players-ejected-from-georgia-vs-mississippi-state-after-collision-at-plate
I would agree that since the NCAA rule says "leaving the dugout during an altercation or fight" is an ejection, it seems like more than 11 would need to go here. Wonder what their threshold was for deciding who got tossed and who didn't?
I guess to me the slide doesn't seem malicious, the catcher is moving into foul ground and the runner slides while trying to reach with his arm for the plate. You could probably argue that there's some 'launching' on the slide but I guess I'm seeing that as an attempt to reach the plate (again the catcher is moving into foul ground giving the runner zero room) and this is all happening in a split second. One question in looking at the collision rule which is fairly moot here since the runner was out, does "blocking the pathway" include with and without the ball? In the case of a headfirst slide, a runner shall be deemed to have slid appropriately if their body should hit the ground before contact with the catcher. If a catcher blocks the pathway of the runner, the umpire shall not find that the runner initiated an avoidable collision
in violation of the Collision Rule.
