Hagos isn't in the game because it is last season's rosters (when he was still with AIK in the 2nd tier). Immonen probably isn't there because he spent most time (if not all time?) with the jr. teams but I will check later on today.
I can also check the attributes for Tuokko and Elomo..
I remember scanning the rosters, Elomo's rated pretty highly (with a big shot), and Tuokko's not rated that highly (maybe a 75 OV). And Gabriel Karlsson and Janos Vas were rated awfully (though Vas had pretty high potential if I remember right).
But Hagos and Immonen (who did spend all his time with the Blues Jr. team) weren't in the game. I suppose next year, Immonen, Hagos, Eriksson, and Granath (has already played in the SEL) should all be in there.
