Another Finn! Can’t wait to hear endlessly about all his deficiencies and lack of IQ
He has actually had some weaker moments and even times, but he's developed a lot in that regard. All in all he may be one of the best available options for a 4th liner who can be very solid defensively and potentially score more than you'd expect from a 4th liner.
I suggested Mäenalanen a couple of times in the Oilers forum so it'll be interesting to see how he'll do in your team. I think it's a good signing, a good chance to get a solid bottom 6-player with a large frame, but not much to lose with a 2-way contract. When he's totally focused and 100% in, which is nowadays the norm almost all the time, he can be a kind of a machine in his role, a difficult player to play against.
