The post said that he wasn't expecting much more than a hit or two and a stupid penalty. That's a pretty accurate expectation when it comes to Reaves. Your response seemed to imply that he didn't take a lot of minor penalties, so I noted that he actually does take a lot of minor penalties. He in fact takes penalties at the highest rate on the team this year. He just doesn't have the raw penalty numbers of others because he sucks so much that he only plays 8 minutes a game, and he hasn't played every game because of healthy scratches and a suspension. I'm not sure why you're so against acknowledging that, and it's relevance when we're seemingly putting Reaves back in the game we're discussing.
I think pretty much everybody agrees that penalties have a negative impact. That said, it's much easier to accept it when they're bringing a lot of positives otherwise like Nylander, instead of negatives. And let's be clear. These players do not take penalties at the same rate. For one, Nylander hasn't taken a penalty every 4 games. Nylander has taken a penalty every 6 games. Reaves has taken a minor penalty every 4 games.
But wait, it's actually so much worse! Reaves has taken a minor penalty for every 31 minutes he has been on the ice, and Nylander has taken a penalty for every 116 minutes that he has been on the ice. That's quite a difference. But wait, it's actually so much worse! That's only minor penalties. We're forgetting about the reason that we're talking about him in the first place. What he's coming back from. That 5 minute major that he took. Remember that? Which means, Reaves takes a penalty every 3.2 games. Every 25 minutes. But wait, it's actually so much worse! That's just counting every penalty the same. But 5 minute majors are so much worse. They're 2.5x the time, and they don't end on a goal. Which means, Reaves has given us 1 minute of penalty time for every 9.6 minutes he is on the ice (playing badly) this year. For reference, Nylander is about one every hour.
