Claiming that there is ostensibly no rhyme or reason to the sport's frequent in-game substitutions, players from across the NHL admitted Wednesday that they have absolutely no idea how line changes work. Honestly, most of the time I just try to jump onto the ice whenever I can, and then Ill come back to the bench when I get tired, said Chicago Blackhawks center Jonathan Toews, adding that the changes are especially confusing following icing calls, when some guys are allowed to change but other guys arent. I know certain players are supposed to go out at specific times and in shifts or whatever, but I couldnt even begin to tell you who, when, or why. Like when were on a power play, there are certain guys who are supposed to play, but then if the other team is on a power play, a whole different set of guys go out. And most of the time we have to sub in and out while the game is still going on. Its just chaos. A majority of players also confirmed they would much prefer having some kind of buzzer sewn into their uniforms to alert them when its their turn to take the ice.
