Swan42 you are going too far back, this is about here and now. I am not suggesting its not viable for him to play reserves for a week. I watched Lobb live against Subiaco and have tracked his perfomances. I mentioned that Swans could play them both.
What people need to think to themselves is, if this is reasonable to have him in the twos for a week, if you know anything about wes. He is a total club man and team player. More dedicated than any player at the club. More humble than any other (to the counter to what you people are saying) - so what makes him walk from this? The answer lies in the football departments conduct and standing to the players.
As for asking about how I conclude the other things. I have spoken with a number of colts/reserves players and associates of the coach.
