We're talking about a scenario where Knies starts with the Marlies in order to be cap compliant day 1 and they can find a way to get him up. There isn't a chance Cowan is prioritized over Knies who is ready to play pro games vs an 18 year old who dominated prospects and a team of half AHLers half pros going at half intensity.
On top of that, when has the Leafs org shown a willingness to rush prospects under Shanny? We even sent Marner back to juniors. Last thing you want is to tell him he made the team, he struggles and it impacts his confidence, you send him to junior with the wrong mindset that he failed or wasn't good enough.
They will hype him up, let him stick as long as possible to be around NHLers and pick up some things, and then send him back with days to go and talk him up about how they think he can compete for a spot soon and all of that.
