When a player goes to a new team, it sounds so wonderful at the start.
Take the case of David Clarkson, for example. His contract was up in New Jersey, and the memory of a stellar 2011-12 season was still fresh in the minds of many of the league's top general managers. As a result, Clarkson became a sought after commodity because he was a tough, physical forward who could also put the puck in the net.
Clarkson eventually signed with Toronto, and that gave him a chance to play for his hometown team.
That sounds great in the summer when everyone is smiling and back-slapping, but that's all forgotten when the puck drops.
For Clarkson and nearly every other new arrival it's about production and nothing else.
That means these players have to contend with pressure. Here's a look at the new arrivals who have the most to prove in the 2013-14 season.
