Soshnikov is a better 4th line player than leivo. A sosh-boyle-martin line would be better than with Leivo. Leivo may be a better scorer but we have enough top 6 players for the moment so for leivo to stay in he'd have to out hustle/grind brown/sosh or hyman
Too early to say conclusively on either player, but from limited viewing I'd say Leivo is better along the boards and in the corners, and a much better passer. I like Sosh, but he's shown some real limitations this season. That line was better with Leivo, albeit for only a few games.
