@pakman said in Lions v Crusaders - Super Rugby Final:
Using the patented play pause technique on the YouTube clip it seems Smith propped when Havili jumped. I don't think he challenged. But to be honest it all happened so quickly I'm not sure Smith had time to think. He certainly was too slow to avoid being smacked in the way through.
So, whilst the red seems correct under the guidelines, it seems doubtful to me that Smith could have done much differently. In which case an accident, not reckless and not a situation where protocol ought to be mandatory red.
Which begs the question of the jumper...
What, you don't think Smith knew the ball had been kicked in the air? 
Once a ball has been kicked it is very, very clear that you can't just run blindly into the landing zone. You have to assess whether you can legitimately contest the catch. If you're not in a position to do so then your absolute priority is to not make contact with a guy who is in the dominant catching position while he is in the air.
If you do, you are playing with fire.
