While the Leafs had a lot of different lineup iterations throughout training camp, the new lineup does contain a few groups that we have not yet seen during the pre-season.
Perhaps the biggest surprise is the fact that Nick Robertson went from skating on the team's 5th line, among other scratches, to earning a look on the 3rd line with Max Domi and Dakota Joshua.
Robertson was a standout during most of training camp, leading the team in shots on goal and holding a share of the lead for pre-season goals. Leafs coach Craig Berube also gave Robertson a strong review following camp, and established that he is a big part of the team, which could dissuade the team from moving him.
There is still time for things to change between now and October 8th, but barring any major shifts in mentality from the coaching staff, or a trade to bring in a top-6 forward, this is likely what we'll see on opening night.
The big question at this point is, what does this mean for Easton Cowan, who was originally expected to make the roster? Time will tell.
