Evidence?
We know Bancroft and Lees will open, Steel will be 3 and Harte 4, Burnham 5, Richardson 6, Poynter 7 Raine 8, Trevaskis/Pringle, 9 Salisbury 10, Rushy 11.
This game: no 4 had to open, as he had in preseason. Burnham was hidden a bit down the order (good choice given what's gone on) which meant Richardson/.Poynter necessarily had to come in early.
No doubt through the season the line up will change because of injury or the Head Coach wanting to blood youngsters or whatever.
IMHO, it's premature to draw too many conclusions from this first match. Not having 2 or your top 3 available is bound to mess with your line up.
