If Knies is able to continue contributing without Matthews and Marner, it will simply give Keefe more options down the stretch and in the playoffs. Also, with Knies playing a little lower down in the lineup, it could also create some mismatches for the opposition that the Leafs can exploit.
Seeing this added grit and feistiness from Knies is a welcomed sight as the playoffs approach. As a rookie, your first full season can be daunting and pressure-filled. To see Knies finally coming out of his shell and mixing it up a little post-whistle is just a sign of what is hopefully to come in the playoffs.
