Maybe in playoff with all emotionnal thing coming with but no i dont think thry would react to a teammate who lost his footing in a 1v1 battle...it was not a dangerous hit from behind or to the head, it was just a 1v1 battle who wasn't finish pretty well.
And like i said earlier, i dont even know what its the difference between that play or knies against nashville i think who lost his footing too in a 1v1 battle and hit the board really hard... except than liljegren had been seriously injured and not knies...
So i asking you the same question, why should be worst against liljegren than knies. The gravity of injury dont make the play worst or not, its the same exact play just with a different result
1v1 physical battle marchand lost control of his stick who goes between liljegren leg and make liljegren losing his footing... so yes its 100% a 1v1 battle where a teammate losing his footing. If liljegren is not injured, ABSOLUTLY NOBODY would talk about it... but the result dont make this hockey play worst, sorry
