There probably isn't any one player on the Tampa Bay Lightning roster that draws more vitriol than Matt Carle.
Since signing with the Bolts as an unrestricted free agent in the summer of 2012, Carle has slowly gone from "nice free agent pickup" to "horrible waste of cap space" in the eyes of many Tampa Bay Lightning fans.
It's fair to say Carle has underperformed expectations for him when he signed with the Lightning, but it's also important to point out that those expectations were in part created from salary he's being paid. Paying for roster players in unrestricted free agency is "overpaying" more often than not, which is why so much of the Tampa Bay Lightning's success under Steve Yzerman has focused on drafting and development, with cost-controlled assets on ELCs and RFA deals.
