I just want to clarify something that's not being said. The problem is not in the opponent selecting whatever "powerhouse" team to win. The problem is that the online players DON'T have an option to back out of the match unless they automatically want the loss.
In years past, if I didn't want to play another "powerhouse" team, I would back out and search for a new opponent. This year, you're just "stuck" with whomever you're matched up against unless you want the automatic loss, AND the problem could be compounded if you and your opponent select the same colored jerseys.
I played one game where I had the Pacers gold jerseys, and I was matched against a Cavs user using their gold colored jerseys. I quit the game in the 1st quarter, because it was just too much of a eye sore. Plus, I kept getting confused which players were on the court. There's nothing worse thinking you're passing to Paul George, but you was LOOKING at JR Smith.
