The Contract: 5 Years - $5.9M AAV (2012)
Patrick Sharp was a very skilled winger in his time, and was always a fan favorite on and off the ice. He is a 3 time Stanley Cup champion just like Seabrook, and was a huge part of the teams success during their golden years in the early 2010's. Sharp signed a huge extension that kicked in during the 2012-13 season, and was viewed as a monumental part of the teams core.
Unfortunately, Sharp only appeared in 28 games during that season, but had 20 points. His 2013-14 season was insanely strong, as he put up 78 points in a full 82 game season. After that though, he really slipped. In the 2014-15 season, Sharp had 43 points through 68 games, and had a -8 plus minus to finish the year. It was clear his play had declined quite quickly, and he was no longer a $5.9M player.
The Blackhawks moved Sharp to the Stars, where over two seasons and 124 games, he put up 73 points. Sharp finished his career on a one year, $800,000 contract with the Blackhawks and put up 21 points in 70 games during the 2017-18 season.
This is a case of Sharp having interest from other teams and giving him a much longer term that he wanted, so he would stay. He played really well for two seasons before declining fast. Fortunately, the Hawks were able to ship him out to the Stars who needed some veterans at the time, and he was given a bigger role that he wasn't going to get with the Blackhawks.
