I'd say they have at least 15-20 unforced icings a game. Say the wings win 50% of those faceoffs that's almost 10 extra offensive posessions for their opponent a game while the wings are losing possible posessions in the offensive zone. It's frustrating to watch, and I basically count it as a turnover even if they win the ensuing faceoff.
LOL. You're not even in the ballpark. Wings have 18 icings so far in the series. Can't determine forced/unforced, but I'd say most icings tend to be unforced. TB has 12.
You can find the info in the play by play reports on NHL.com. Far too much work to go through the whole season, much less to do so for the whole league.
Like most other stats, I would assume the Wings are between a bit above or a bit below average.
