What is the diffrence between :
1- ( Team Bob ) and ( Bob's team ) ?
Hi, and welcome to Using English.
Team Bob is quite informal. If you say you're on "Team Bob" it COULD mean that Bob is your team leader, or that you are a part of the group of people who are hoping that Bob will succeed in something.
In that Twilight series, I guess there are two male leads who both want the main character's love. One is Edward, I think, and the other is Justin? (I'm not sure of their names, actually.) But people who think she should be with Edward say that they are on "Team Edward."
In most situations, "Bob's team" will be more common.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
