There, you said it in the bolded. Physicality is important, BUT so is speed. That means Kyrou's speed should be factored in. And its not being considered by many here. That is my argument. Not that Brady is bad, but that he is being overrated by many here based on his physicality, while ignoring Kyroi's speed and the effect has.
They produce at somewhat the same ppg pace, a nod to a litttle more for Tkachuk but not much. Both have defensive issues. But Brady is being put 2-3 tiers above Kyrou by many due to physicality while ignoring Kyrou's speed and game-breaking ability. In a vaccuum, Tkachuk is the better player to have than Kyrou, I am not arguing that. But its not by a ton. Factoring in 3 less years on Brady's contract and the AAV he will demand on the next one, its even less if at all, imo.
If you don't want to trade him, that's fine. Say he fills a need and we have other fast players. But saying It would take Kyrou++++++++++++++++++ is just insulting our player when it isn't necessary.
