Antoine Vermette is 32, just made $3.75M and will be looking for a raise. He had 13 goals and 38 points last season with a -25. -2 of that was from his time in Chicago and he only had 3 points in 19 regular season games there. In the playoffs he put up 7 points in 20 games and has a career 25 points in 78 playoff games. 2009-2010 was the last time he had more than 45 points and you want him to be the second line center.
Desharnais is 28, is making $3.5M for the next few years. He had 14 goals and 48 points last season with a +22. He had 3 points in 11 playoff games. You might say, "Look! Vermette is way better!" but you forget that Vermette had only 3 points in 11 playoff games at that point, same as DD. DD's career playoff points are 13 in 38 games. He has yet to in his career play 50+ games and not have more than 45 points. In 09-10, the last time Vermette had more than 45 points, Desharnais was just starting his NHL career. And you want to replace Desharnais with Vermette.
Pure craziness.
