(Summary) When typing: "/scoreboard teams list (team_name)" into Command Block and giving it a pulse, it does not produce desired effect

What I expected to happen was...:
I thought the command block would broadcast all players on team to the chat console for all players to see
What actually happened was...:
Command Block did not execute any command

Steps to Reproduce:
1. Create a team using the /scoreboard command. Join said team
2. Type /scoreboard team list (YourTeamName) into a command block
3. Give redstone pulse to command block
