The ice time argument is flawed, to be perfectly honest.
Games are not 60 minutes 5 on 5. There is powerplay, there is PK. Matthews & Tavares are going to be out on a top PP most of the time together. Domi would be a great player to have on a 2nd powerplay unit.
In 2018-19, Tavares saw 19:05 in ice time. Matthews 18:33. Kadri was 16:11.
That being said, look at the ES TOI:
Tavares 16:18, Matthews 15:57, Kadri 13:35
Plus, I think with Domi, you don't view him as strictly a #3C like Kadri was... I think it varies between him & Spezza depending on your opponent.
