Arguing Cole over Kunitz is perfectly reasonnable. As for Kostitsyn, i already said i'd pick Kunitz for 1 year. Kostitsyn is expect to start on the 3rd line anyways, so it doesnt help Kunitz cracking the top 4.
Before you label me as a perfect homer, i'd like to mention the 3rd lines duties for Staal in Mtl are completely ridiculous, he'd be fighting for the top spot with Plekanec imo.
Unless Staal suddenly becomes a near PPG player, there's no way he competes for Plekanec's spot. I would take him over Gomez for 2nd line duties in a nanosecond though.
As for the Kunitz vs Kostitsyn debate: for the coming season, Kunitz over Andrei? Sure, why not. For mid/long-term, not a chance. The 6-year gap is a non-starter, and some people in this thread really seem unaware of AK's actual upside, which is a good but not great power forward with game-breaking abilities which, even though are not displayed every single game, no Habs forwards, including Kunitz, are able to bring.
