Tavares has done it a bunch in the 4 years he's been in Toronto, and he did it a ton through the 9 years he played on your team.
The poster you replied to didn't say "if he has the right linemates". You inserted that all on your own. He said "if the ingredients are right".
The poster you replied to also didn't say anything about putting Marner on Tavares' line.
You also seem to be making the incorrect assumption that two line-drivers can't be put on the same line.
Both Marner and Tavares are line drivers.
I know that you are weirdly obsessed with the idea that I'm an Islanders fan and not a Leafs fan, and that you also have some bizarre idea that if you mention that falsehood you can automatically disprove anything I say, but you're wrong.
For starters, I hadn't pay any attention to the Islanders since the '80s, until Komarov went there. In case you don't know, that was after Tavares left.
Second, Toronto has always been "my team". There have been many other teams over the years that I have enjoyed as well, including the Islanders, Montreal, Detroit, Edmonton, and St Louis, but Leafs have always been my team.
You are right in saying 'The poster you replied to didn't say "if he has the right linemates". He said "if the ingredients are right".'
But I never claimed that he did. I said 'The poster I replied to said he could "if the ingredients are right", which means "if he has the right linemates".'
You are also right in saying 'The poster you replied to also didn't say anything about putting Marner on Tavares' line.'
But again, I never claimed that.
