The problem here is that a guy who had 15G is a “major blow” to you team.
That’s some serious depth issues if Bobby McMann being out hurts you that badly
You're underrating McMann by referring to him as just a 15-goal scorer, it doesn't accurately reflect how his season has gone
For the first few months of the season, he was used primarily on the 4th line and averaged around 9 minutes a game playing with Kampf/Gregor. You're not going to score in a role like that no matter how good you are
The change came on Jan 13 when he moved up in the lineup due to a couple of key leafs forwards out due to illness. He was originally supposed to be scratched this game but ended up playing and scoring a hat trick. Since then his year turned around completely, scoring 13 goals in his final 29 games (37 goal pace). On top of this, his linemates changed, with his most common being John Tavares in a top-6 role
He's also reliable defensively and allowed us to move Knies down the lineup. Knies has been struggling in a top 6 role and putting him against weaker competition allowed him to play the best hockey of his career. With McMann's injury, he's forced back into a role he isn't the best in
Also, I didn't say McMann on his own is a major blow, it's him + Nylander. For some reason, you keep repeating a line without reading what I actually wrote
