Starting from the goaltenders. I think it is obvious we are going in to next season with UPL and Levi. I think another year in Rochester would not hurt Levi it would only do him good, but if the season not starts well I hope they won't hesitate and bring in a replacement, they can probably find one cheap. An UFA veteran like Lankinen(or someone else) is not interested to be back up for one year and maybe also share games with Levi.
On defense the already mentioned Pesce, Roy, DeMelo is top names that might become very expensive. But we need a RHD so I hope Adams is trying. An interesting option, a trade where I think all parts might be winners, both players and teams, is Byram to Calgary for R Andersson.
Of forwards Stephenson is a favourite as a dubble cup-winner. Monahan could improve our powerplay. I think of Östlund as a same type of player as Teräväinen, so why not bring Turbo here? Rod Brind'Amour has always praised Teräväinen for His work and two way play. As an outsider I pick Arvidsson, I just like him, he seem like someone who hates to lose.
I am not that good att fourth line players, most interesting players has already been mentioned, but I think Craig Smith (DAL) needs to be mentioned.
