Why, you ask?
Because, since signing with Tampa in the summer of 2012, Carle has been a 'lightning' rod (no pun intended) for criticism. His play has underwhelmed in a significant (read: enormously monstrous) way, especially when you compare it to the $5.5M cap hit he carries/carried:
As the tweet says, you can't have a guy on your roster carrying a $5.5M cap hit who does... that. It wasn't good enough. No matter how you slice it, there are better ways for the Lightning to be spending that money. It's hard to argue against Steve Yzerman's choice to end Carle's second tenure with Tampa Bay..@MimicoHero's chart on Carle sums up why he was waived today: You can't pay $5.5M per for a depth defender. pic.twitter.com/IuSrdGFoO4— Michael Stuart (@MikeStuartTLL) July 1, 2016
