But, but, let's trade Schenn and Couts because they're not 1st line caliber!
Voracek's development should be a lesson in player development, these guys don't show up on day 1 and become stars (ok, Gretzky), they develop over a number of years and have to physically and emotionally mature to reach their peak.
So as long as they have talent and the work ethic to improve, focus on their development, not their shortcomings.
Of course it is important to let the players develop properly, but there are reasons why players might not be successful right away, ex. Ice-time, linemates, injuries, physical development.
But certain players just don't have the skill set to meet lofty expectations. If we expect Couturier to put up 70 points a year, and shutdown D, you will be disappointed. If we expect B. Schenn to be a PPG LW that will solve our LW problems, you will be disappointed.
Not all players develop to their full potential. It just happens, people will struggle for various reasons. Sometimes it is better to sell high than not at all. I am a B. Schenn hater. I don't think he will ever be more than an ordinary 2nd line LW at the best. If we trade Schenn I will not be angry as long as the return is somewhat acceptable. Couturier on the other hand, I consider almost untouchable.
