Wow, that's a pretty brazen thing to say to you. Were they insinuating that you were carrying everyone on the team? BTW, I seen everyone on both sides make some odd mistakes.
No - they implied the opposite of what you said. They said if Dennis were to lose and the team lost overall -- it wasn't his direct fault - it was the fault of the team. Conversely, if Dennis won and the team won--- it wasn't won BY Dennis specifically, the team pulled off the win (which is the correct way to view team events in general).
