Fans may want to believe Copp and Compher were signed to help take the next step, and if that next step was from the basement of the NHL (17 wins, .275 points percentage in 2019-20) to the mushy middle, maybe those fans are right. But they were most certainly not signed to be the straws that stir the drink.
They are still on the roster because their contracts are not expired. I have said before, the market is the market, and the market means you pay too much in dollars and in term, especially if you are a basement dweller. It sucks to suck.
They are also still on the roster because nobody has stolen their jobs. I’m sure there have been times where Stevie would have liked nothing more than to trade away Compher and even retain salary but he couldn’t because nobody was ready for his minutes. And they are still on the roster because Stevie was more realistic than fans about how bad the roster was and how long it would take for the kids to be ready.
They have done their job, which is to eat minutes and years for a rebuilding franchise. There is no glamor in it, no glory, but the pay is good.
