The speed thing is an issue but it's self-correcting. No need to make any moves because the team is slow now. Botterill knows this too. He was part of the team in Pittsburgh that increased team speed by bringing up Rust and Sheary, and made a smaller trade for Hagelin. There's no need for a huge move because the players who can help are already in the organization.
Bailey is already up. Baptiste is fast. Nylander has wheels. Guhle might be the best skater in the organization after Eichel. And Mittelstadt and Asplund are on the way. You add them to Eichel, Reinhart, Okposo, and ROR, and you get a fast team. Two years from now:
Girgensons - Eichel - Nylander
Asplund - ROR - Okposo
Mittelstadt - Reinhart - Bailey
Fasching - Larsson - Baptiste
That's a fast line-up.
