Star players aren't head hunters like those guys were. This is why they were always going to be treated more harshly be the refs. If Mcdavid hits someone from behind does he deserve the same kind of scrutiny as Matt Cooke did? You can tell which one of them was doing it intentionally based on reputation. Refs can still make reputation calls, that's not necessarily a bad thing to keep those players in check.
Star players are just as dirty, i used the worst of the worst. You did exactly like ref. A call is a call, regardless of who did it. Marchand is a notorious rat and gets away with a lot that would land a goon in front of the review board much more easily. Why should he get different treatment on a slew leg than cooke. A kick is a kick.
Chara for years would be sighted as a clean player bevause they would always pass on his suspensions. So despite a number of times being before the board, because of no "priors" he would again get off with no suspension. ( Not picking on them because of boston just great players gettting a pass) you would also note chara is less likely to get a suspension than marchand because of his better rep. But it doesnt change a dirty play.
Think of it like your driving record. You are driving like a crazy person. Maybe you got a great personality or the officier is of the opposite sex and lets you off on a warning because your record is clean. This happens 4 times in a month or two.
Yet another driver has a violation for rolling through a 4 way and another for driving 120 in a 100 in the last year. Maybe one of the quota tickets that " dont exist". Much like managing the game, If you get pulled over and they see 2 infractions, and you may not have been pulled over outside of those 2 events , they may still assume you also got let go or had your penalty reduced on a occasion, clearly you haven't learned your lesson. Ticket for you.
Now the same guy has 3 marks on his license while the first one has been pulled over seven times and only had a failure to show insurance or something minor. Next time both are pulled over who is more likely to get the ticket given the same cop in the same mood? The guy with 3 strikes will more likely get a ticket than the guy pulled over more but never getting the ticket. We also know the bad driver is just really good at making a case to not be punished, even if they are almost definitely the more likely to commit again.
Sure there is that drunk driving Clutterbuck with 3 tickets for speeding, 4 for passing on the right and 20 parking infractions. But it doesnt mean that his doing 115 in a 100 is worse than Crosby driving 90 in a school bus loading zone. In the nhl the one guy keeping up with traffic, but with a record will easily get a penalty from his small infraction. Meanwhile crsoby hit a small chiled, but only winged her, so he gets off with community service.
