The most difficult part of following the Penguins' prospects in juniors, college, or Europe, is easily trying to keep track of the Finnish prospects, for a few different reasons.
The way I follow a lot of these guys is from following their teams on Twitter, I follow each of their teams. Obviously, they're not posting in English. That part is fine, since I can get away with just skimming for their names among all the tweets in Finnish, which makes me feel like Ed from Good Burger:
The more difficult part is that, unless it's a prospect like 20-year-old 2019 seventh-round forward Valterri Puustinen who is a mainstay on his team's roster in Liiga, the top men's league in Finland, they could be anywhere.
