According to that clown Doug Maclean, Chara is an absolute gentleman.
The lack of meaningful punishment of Chara after his attempted murder (OK, reckless endangerment) of Pacioretty had everything to do with his 'gentlemanly' reputation around the league. Secure in the knowledge that Chara is a swell Joe - after all, with his size he could be wiping guys out every night and chooses not to, right? Therefore he is obviously incapable of ever intending to do anything as radically dangerous as deliberately slamming a kid's face into a steel post, right? - they were relieved of the obligation to consider any facts or any context. E.g.: that Chara had been trying to get Patches for the two games prior; that Patches explicitly said he felt he was a target before the game; that the game was out of reach and therefore a classic scenario for a 'revenge' hit (c.f. Bertuzzi/Moore); that Chara is an elite athlete extremely familiar with that ice surface and therefore 99% likely to have known exactly where he was steering Patches; that the hit was interference and therefore in no sense an instinctual 'hockey play' (i.e., it was a premeditated decision); and that his forearm clearly drives Patches into the stanchion.
That's OK, though. Chara's a good guy. Besides, his teammate's dad was responsible for discipline, so that makes him an even better guy. And that punk Pacioretty never should have shoved him after scoring a GWG earlier that year anyway. He deserved it. And if he had been permanently handicapped or killed, which were equally likely outcomes - it's sheer luck he merely suffered a severe concussion and broken neck - well, he would have deserved that too. Just like Crosby deserved to have his arm broken (Cherry) for that stunt goal he pulled in junior and Subban deserves anything he gets for being a mouthy black guy. All part of the sacrosanct Code.
