Olofsson will be on the Sabres roster this season. Nylander will either be gone next week or will also be on the Sabres roster. So they're leaving the pipeline.
Davidsson, Asplund, Pekar, Routsalainen, and Thompson don't project to top six forwards.
Cozens does project to a top six forward, but he's at least two years away.
Only Asplund, Pekar, Routsalainen and Thompson will be in Rochester next season.
If Botterill can acquire a center and winger through free agency or by trade, they should be all right, but it's going to be expensive.
