If the secondary teams aren't allowed in the B3, there could be another B3 tournament on Wednesdays for secondary teams. It could be called the BuzzerBeater's second Best, or something.
I voted against for none of those reasons. I like the one team per person idea. For example, I'm torn whether I should start training with my team, or should stick with my strategy of not training and maximizing my money to buy players. If I get a secondary team, I definitely won't change my strategy with my primary team, and will simply use my secondary team to enjoy the training aspect of the game. In other words, the second team will effect what strategies I use for my primary team. And I won't run my secondary with what I perceive to be the best strategy, but will use it to do things I'm not able to do with my primary team. With one team per person, using one strategy, is the death of trying out other strategies. It adds risk and makes the game more interesting, in my opinion. There is no back up team, no fall back plan.
